Help, my Sims icons are missing from Panel!

@ThatsSoGallistra  I'm probably not going to be able to give you better advice than you'd find at NRaas, but here's what I would do.  First, add ErrorTrap to the mix.  Overwatch is great, but having both is better.  You'll also want to make a backup copy of your saved game, if you don't have one already.  (By the way, if you have several backups, the best thing to do would be to revert to a copy from before the problem surfaced.)  You can go into your Saves folder inside Documents\EA\TS3, right-click on the folders for your save and its game created backup (i.e. SunsetValley.sims3 and SunsetValley.sims3.backup), select copy, and paste the folders elsewhere.

Before loading the game, make sure to delete the cache files in your game folder, if you haven't already.  (These are CASPartCache, compositorCache, scriptCache. simCompositorCache, and socialCache.)  In fact, quit to desktop and delete these after every troubleshooting step, whether you've saved your progress or not.

So, load up the save with the family that you were playing immediately before you switched to the one that isn't working.  While that house is active, click on the map tag for the borked household and do a MC Reset Lot.  If you already did this while a different household was active, or it doesn't work, then the next step is to go to Edit Town, evict the borked household, copy their house to the bin, bulldoze the lot, replace the house, and move the family back in.  If you do this all in one Edit Town session, without saving the sims themselves to the bin and replacing them, they should keep their jobs and relationships.

After doing the above, don't switch to that house right away.  Use "save as" to rename the save (so you have another backup), quit, clear your caches, reload, do another MC reset of the borked household just for good measure, and then switch to it.

By the way, with ErrorTrap in place, you'll probably get some scripterror logs.  If you're still not getting anywhere with troubleshooting, you can zip those errors together and upload them either to the NRaas site itself or to a free third-party hosting site like Mediafire.  The NRaas people can then read through the logs and tell you if they see an issue that can be corrected.

I do in fact have Overwatch, Master Control, Error Trap, Debug menu. I did try reseting the lot and reseting everything, but while in the borked house. So I'll try while at the one before it. I usually do delete all the cache before every start up. I also didn't see any .bad files, just the regular and the .backup. I also delete the Script error logs because the site I read what cache to delete said to delete the script errors. W/e is there will be from that current game play. I hope that would be enough if needed? I'll try the rest of what you said that I didn't try yet. Thank you.

Welp, none of that worked. I also didn't realize that the grandson wasn't a YA yet, for some reason he was still a teen when he should have aged up w/ his cousins by now. So I was in a different house and went over there to shift click on him to age him up and it was giving me messages about how he couldn't age up, that there was an issue w/ aging up and the [mod name redacted] was not responsible for the error. then some Tore about producing age up outfits, then messages about each individual outfit it was producing, and he finally aged up. So I saved it, went to the house, no such luck. Same issue as before. So I moved him out of his mom and dad's to a new house. And there was his icon, and one of the dog's. He took a dog w/ him. I moved his girlfriend in, so I can wed them, but before doing so I wanted to save it. Annnd I got a save error code 12.   T_T

So Idk if the corruption was w/ just the grandson, or if there's still corruption w/ my son's Sim and/or his wife. Didn't get that far to check because I exited out since it wasn't letting me save. If there is corruption w/ "sonny" and the Mrs., (who are elders right now) then I'll have to just let them expire on their own to get rid of the corruption. Because it is just one household that's the problem. All the other families in town are functioning normally. So I guess I just need to improvise and get through the next 2 generations before I cal it quits and start all over again, and maybe in a different town.

[Edit: removed reference to a certain mod.  —puzzlezaddict]

@ThatsSoGallistra  You didn't mention having that other mod in play before (and please don't name it on this board), but that's almost certainly the cause of your issues.  The mod doesn't play nicely with several NRaas mods and is even known to shut down some of their corruption-preventing functions.  This other mod is also not conducive to long-running saves in general.  So it's not surprising that you're having so much trouble.

If you want support for that mod, you'll have to ask at the host site.  But you can't remove it from a save that has had it in play without completely corrupting the save.  You probably can't even rescue your sims—they'll have been exposed to extra trait slots and the like that a save without the mod in place won't be able to handle.  So your choices are basically to either play this save forward until it becomes impossible, or to start a new one, without the mod in question.

I'm sorry that I can't help more, but there really isn't much you can do about corruption from this source.
