The page keeps losing all data mid-use while getting that error? This happened before once and then it was fine but now it returned again?

I'm getting the Cannot read properties of undefined (reading 'characterId') error again, I don't know why

For the past few days I've been having trouble on character chat, I keep losing all my chats, when loading any saved file after a while all chats become inaccessible and and the "Cannot read properties of undefined (reading 'modelName')" error pops up. I've occasionally had the browser delete the chats but I would save them so loading them wouldn't be an issue but this time it's rather persistent and I think it's a different issue. I don't know if it could be because I've reached over 3000 chats on one of the save files because that's when it started bugging out, however when starting from the scratch it still keeps doing this and I'm wondering if anyone else has the same issue?

I really like the new model, it can be weird sometimes but with enough training it can be fixed and I don't mind the aggresiveness, it just needs to be applied only when prompted by the char description. I wish the violence isn't toned down, it seems like the dev's doing something about it...
