@Dusky they wouldn't do anything even if they know how to reproduce the bugs.
I also think that even if you provide one method, there will be another and another. The whole problem is the animation physics and how it was written by Rockstar, how much it depends on fps so I don't think it can be ever fixed, only if they or mta rewrite it fully which cannot be done without changing the engine. GSG had the opportunity with DE, they switched to UE4 but it was a silly remaster not a remake
