Haven’t been able to extensively test this but I and a few others have been experiencing issues with saved parameters sticking after a world hop. These avatars have not been reuploaded or modified, the only change has been the recent update. And yes, the parameters are marked as saved, they have been working fine prior. The mysterious part is that some saved parameters are fine but others are not.
This is a known bug and a fix for it is in progress that should drop in a patch in a couple of hours.
