Sims 4 Mermaid's kiss and Siren's Call options don't appear

@H4RS3SIS This may or may not be helpful but I thought it would be a good first step, just for eliminating...

The large, recent patch/update brought in many changes. These types of changes effect many aspects of the game. Mods and CC involve code that can sometimes clash with the updated game code, and even cause damage, if not properly updated to match the new changes in the game's codes. Even after you remove the Mods/CC, sometimes damage can linger in the game code that can be addressed by removing cache and repairing. I would recommend that you do the following in this order:

• Exit your game then exit Origin. Copy the Mods folder from your 'The Sims 4' folder onto your desktop (for future reference) then delete the mods folder and the localthumbnailcache.package file in your 'The Sims 4' folder and restart the game and so that the game will re-create the folder.
• Then run a game repair [ Open Origin, click 'Game Library' then right-click Sims 4 > Repair Game ]. Make sure to let it run until it has completed all repairs (it will do the basegame first, then run through each of your expansions/packs). After that, please see if the issue has stopped.

If It fixes the situation I would recommend that you check with the Mod and CC creators to see if there are any known issues with their Mod/CC clashing with the update and if so do they have an updated Mod/CC that will address the changes in the game's code from the update. You can then re-add your updated Mods/CC one at a time to see if one was conflicting with the function/causing the glitch - but do not re-add the old config file from the old mods folder, as it is possible for it to have become corrupted also.

Please confirm if doing (the above (even if you did previously) did or did not help so we can eliminate this possibility. Thank you.

Revision:

I have turned two sims into Mermaids in my game (a couple - male and female), and in both cases, while in Mermaid form only (none of this works while they are in human form):

• They are both able to use all of the Mermaid options, including the Mermaid's Kiss and Siren's Lullaby (4 versions)
• Both are able to use the Mermaid's Kiss option only toward a human or Mermaid that is in the water.
• Both are able to use Siren's Lullaby (4 versions) toward a human or Mermaid that is in the water.

I just tried this and now my entire mods folder has stopped working. All my mods (I have over 1.2k) are separated into folders and I'm adding each folder one at a time to make it quicker and so I can narrow it down more easily if there is a problem. But non of them are loading when I go into game now. So thanks for the advice but whilst it does fix the problem of not being able to use the mermaids abilities it just creates another problem (for me at least) with the mods folder 

@Xhloemaee Let's try a reset with your game, then deal with the Mods folder as follows:

Please try the following in this order:

• Exit your game and Origin.
• Move your 'The Sims 4' folder ( Documents > Electronic Arts > The Sims 4 ) to your desktop. (Save this "The Sims 4" folder for reference.)
• Then start the game, and a new 'The Sims 4' folder will be created by the game.
• Exit your game and Origin.
• Now re-add a copy of the 'options.ini', 'screenshots' folder, 'saves' folder, and 'tray' folder from the "The Sims 4" folder on your desktop into your new "The Sims 4" folder ( Documents > Electronic Arts > The Sims 4 ). Replace/overwrite the newly generated files/ folders with the old files/folders from the desktop "The Sims 4" folder. 

Now see if your game will run properly with the newly created empty Mods folder. Don't add the old Mods folder to the newly created The Sims 4 folder.

Now you can re-add your Mods/CC via the 50/50 method since you have a lot of them:

• Divide your Mods/CC from the folder on your desktop in half.
• Add one of the halves back into the game’s Mods folder. Now re-start the game and see if the issue is still gone in the vanilla/new game-save you made.
• If the issue did not re-appear with those added Mods/CC you can try adding the 2nd half from the desktop. If the issues did re-appear, try only adding half of those mods and see if the issue is present in the game...
• Continue in this pattern dividing the folders’ contents in half then half again as needed to eliminate in groupings which Mods/CC are causing the issue.

Once you find the Mods/CC that are causing the issues, check with the Mod/CC creators for updates that may fix the issues. Note: Do not re-add the old config file from the old mods folder, as it is possible for it to have become corrupted also.
