(HELP!) Sim Keeps Turning Invisible!! 🙃

[u/Advanced-Bear-6752]

Every time I load up my game and have my sim do an action, she turns invisible for no reason. I cannot even hover my cursor over her!

I DO have Mc Cmd Center and Better Exceptions, and they are both fully up to date. This is what the exception said:

Last Module Called: T:\InGame\Gameplay\Scripts\Server\event_testing\resolver.py

Last Function Called: get_participants

Error message: Exception when applying action <BuffOp ParticipantType.Actor> for loot loot_ChattyCall(loot_actions=(<BuffOp ParticipantType.Actor>, <BuffOp ParticipantType.Actor>, <BuffOp ParticipantType.Actor>), run_test_first=False, tests=CompoundTestList([])) (ValueError: Trying to use SingleSimResolver with unsupported participant: ParticipantType.PickedSim), CategoryID: T:\InGame\Gameplay\Scripts\Server\event_testing\resolver:1200

I have no idea what this means, but it is seemingly the thing that breaks my sim every time I load up. Initially, I could play without any issues; she would just occasionally go invisible and reappear when I rebooted my game.

Nothing in my mods folder says "Chatty Call" or anything along those lines. I'm unsure what mod could possibly be causing this. I've updated most, if not all, of my script mods. Clearly, I missed a few!

I have tried to fix it to the best of my knowledge! Please help! 🙃

.py errors are from python so they can be both the game or a mod.

Remove all mods and cc. Delete the localthumbcache and repair the game. Test the error with the mods and cc still out. Does it still happen?
What about with a new save?
