Bitter Sentiment stuck for not being invited to a wedding my sim was part of

Yeah, I checked mccc all i could try there was delete the relationship entirely which crashed my game once I tried both to get to know each other again since the game isn't used to the mother having no relationship with her daughter I suppose. 
I did in my frustration however just cheat away the marriage itself with the UI Cheats Extension I believe, going the extra mile to just remarry with only their two kids being invited and it seems to have worked. 

It's just insanely frustrating having to pay and deal with a marriage again simply for the game not functioning properly giving me that sentiment and having to figure out how to actually remove that kinda stuff since it was literally game breaking in a way where the sim who thought she wasn't invited was constantly autonomously being rude to her mother simply because the game decided she wasn't invited while she was even one of the special roles in the ceremony.
Once they added sentiments they should've also added a way with ingame cheats to remove them permanently without them reappearing literally every time the sim sees the other sim because when i actively tell the game I don't want this sentiment to be a thing why does it think I actually meant "wow what a good idea give it to me again" or at least have them work properly with being gone once their value = 0
