Hello Saruwike,
I'd like to look into this issue further. By any chance, do you have saves from both before and after this issue occurred?
If so, could you please submit those saves and the output from our SupportTool via our ticketing system?
For help with that, please take at the "If you still have issues:" section on the page below:
