[FIXED] [IL] Sudden Chill, But Not From Swimming

This happens to my Sim, too. She has Iceproof, Waterproof, and maximum Fitness (all before installing Island Living). 

I just started experiencing the same thing in my game, on one of my two new sims. Important to note - I have a completely vanilla game, and NO Seasons installed. Base game, RG, IL and freebies. No cc/mods - never used.

I have 2 newly created sims living in Sulani. Both are in the Conservationist career, one in each track (but the inappropriate sudden chill moodlet began before they chose their career tracks so doesn't appear to be related).

The one who developed the issue is a Child of the Islands, Self-Assured & Genius.

The one who has not experienced this yet is a Child of the Ocean, Genius & Active.

Reading through the other posts, some similarities with others posting may be low swimming skill (instead of low fitness?), self-assured trait, Child of the Islands trait (although the ones that don't even live in Sulani or have never been to the world probably don't have that trait), and drinking or making Kava (again, doubtful but possible for the ones not playing IL). Since the Kava drinking will give different moodlets depending on what the sim is doing (drink it before bed, and you'll get the "well-rested" energized moodlet from sleeping; drink it during the day and you get the "calmed" happy moodlet), I'm wondering if the "sudden chill" moodlet is accidentally linked to making the Kava?)

**edit - I'm not sure about any other times, but I did notice the last two times this has happened for my sim, she was wearing her bathing suit even though she was not swimming. Would be interested if anyone else has noticed this?

As requested:

Saves in folder "SuddenChillBug-BeforeMoodlet" is from last save before the sim Sefina Kalua got the "Sudden Chill" moodlet. From this point, she finished fertilizing plants, then I queued her to Drink Kava from the fridge (to reduce the tense mood from the volcanic activity) and then "sail here", which would have had her leave the home lot and use her Conservationist canoe to go to dolphin buoy area on the east side of the map.

After drinking the Kava, before the queued "sail here" task loaded, she got a "calm" happy +1 moodlet from the Kava, and then got the "Suddenly Chilled" moodlet, supposedly from hitting a cold spot while swimming. (She was not swimming nor queued to swim; she was still on the lot) The last time she did any swimming was at least 24 sim-hours prior.

Saves in folder "SuddenChillBug-AfterMoodlet" is directly after she received the Sudden Chill moodlet. She still has the "sail here" task in her queue, and is standing at the edge of the home lot. It is apparent she was not swimming. 

Spoiler

This is Base Game with Romantic Garden, Island Living, Holiday Pack & Grim's Ghoulish Guitar. No Mods / CC - never used. I do not have seasons or any other packs installed, other than IL & RG. In this case, she had a previous tense moodlet, I do not remember for certain but I don't think she had one the last time she got this "sudden chill". That one happened when she used the toilet, but I don't have a useful copy of the save.

I DID notice that the last couple of times this has happened, my sim was wearing her bathing suit, even though she wasn't swimming. Will keep an eye out for that in any more cases.

Let me know if you need any further info.

I also have a sim in the conservation career. When she is at home inside her house she'll randomly get chilled and start freezing to death. Every time she gets a "sudden chill from swimming" moodlet even though she hasn't been near the water.

Unfortunately, this bug spread to my other IL sim. His traits are Child of the Ocean/Active/Genius, Conservationist - Marine Biologist, and had just completed Practice Pickup Lines was queued to go talk to his girlfriend romantically. Several sim-hours after any swimming, no bathing suit, has not had or made any kava, is level 10 fitness and has the long-lived trait from finishing the bodybuilder aspiration. The only thing similar between this time and the other sim's inappropriate moodlet is that both had another uncomfortable moodlet present before getting the sudden chill.

@SimGuruNick - I updated my share to include these save files. 

Edit 7-11-2019: Update - my Child of the Islands sim just got a "sudden chill" on waking up and walking to the bathroom. She already had an uncomfortable moodlet from needing to pee. Moodlet solver does NOT take this moodlet away.

I have this too, but with a teen in Willow Creek (in Brook Bungalow). Traits are Self-assured & Bookworm, aspiration Bestselling Author.  He's not been swimming - at all, ever - but gets this moodlet when walking down the hallway from his bedroom to the bathroom. Screenshot attached is the second time (he walked from the bed with the Zzz that haven't quite faded yet).

No mods/cc. All packs.

This just happened to my Conservationist Sim (Ocean Observer). He was on his way to snorkel in Mua Pel'am but had not reached the water yet.

After reading a lot of the resto of the comments, here is a list of traits and circumstances involving this particular Sim:

Summer (13 of 14), Sunny, Hot, Windy, Fitness Level 10, Self-Assured, Active, Child of the Ocean, Long Lived, Laid-Back, Marketable, Stoves and Grills Master, Great Storyteller, Antiseptic, Steel Bladder, Speed Cleaner, Heat Acclimation, Gym Rat, Waterproof Sim, and High Metabolism. Sim is wearing a swimsuit.

I hope that helps establish a possible pattern! I couldn't see one...

Please!!! Is there ever gunna be a fix for this sudden chill issue?? I just started a new legacy sim and she's constantly getting the Sudden Chill from swimming moodlet and she turns either blue or white it's the middle of summer! I don't want her to die!! Please fix asap. 

Product: The Sims 4
Platform:PC
Which language are you playing the game in? English
How often does the bug occur? Every time (100%)
What is your current game version number? 1.53.115.1020
What expansions, game packs, and stuff packs do you have installed? All EPs. All GPs except Vampires. All SPs except Toddler Stuff.
Steps: How can we find the bug ourselves? All I know about how to trigger the bug is that your sim must be swimming and then you either exit to manage worlds or you cut to another sim who isn't around. Like, if Sim 1 is at home while Sim 2 is at the beach swimming. You would switch control over to Sim 1 while Sim 2 is swimming then pull Sim 2 over to Sim 1 by using the bring "sim's name" here.
What happens when the bug occurs? The sim shivers and turns blue for an extended period of time. The moodlet says Sudden Chill (From Swimming) - a sudden cold spot in the water envelopes "sim's name". The moodlet occurs even when a sim is not swimming.
What do you expect to see? I only expect to see my sim cold from swimming when she is actually swimming.
Have you installed any customization with the game, e.g. Custom Content or Mods? Not now. I've removed them.
Did this issue appear after a specific patch or change you made to your system? Neutral/Not Sure

Basically, Tessa, my sim, becomes light blue and shivers at random times. I check and the moodlet says from swimming. Moodlet solvers do fix the problem temporarily but do not permanently fix the problem. The problem started after Tessa went swimming the ocean and I cut back to her husband, Griffith, who was at home. I brought Tessa home and the next sim morning, she got cold from swimming even though she had just woken up. She remained blue for about 3-5 minutes before returning to her normal skin tone. The moodlet never leaves even though it is only supposed to last for two sim hours. (I did remove the cc / mods, but after seeing that problem persisted, I added it back)
