๐ค I tried to copy + reflect a hairpiece only to get this error. The file is able to save again if I delete or undo the new piece. I tried going back to 4.2 to see if it works the same, and it did. It seems to be happening to this hair piece specifically because if I try anything else (add a new paremeter, deformer, etc.) the file is still able to save afterwards.
I've try looking at past threads with similar issues and some of the suggestions were saving the file under a different name or making sure it's saved at a location that isn't sync with anything. I tried those methods and it still didn't work, and I only have one local disk and it seems to have enough space (I'm not tech savvy, so if I did miss something - apologies and please correct me ๐ญ)
Truthfully, this isn't the first time I had this error while working on this model. Those times were easily resolved by just undoing several steps and redoing it (Thankfully, they weren't big things). In hindsight, maybe I should've been more concerned about it, but I just thought that since 5.0 is still pretty new I'd just need to give it time.
If I have to rerig the hair physics; It's fine. I'd just prefer to be able to reflect afterwards and keep things symmetrical if possible ๐ฅฒ
