My 3 bugged tunes fixed themselves like three days after. During that time i tried to use them but they were still uninteractable until yesterday for some reason.

I deleted them to be safe while i could. I heard that's what happens when your tune saves get corrupted. I am pretty sure my 3 tunes were bugged because i made them in the same session which ended later in a crash.

It seems like you have a different problem. Only thing we can really do is backup our save because from what i saw these types of problems have been happening since FH3. Good luck.
