Weird movement of attachments

[Nicholas Melchior]

Something very odd started happening today that has not happened previously. I attached a hat to my head - one I used to wear regularly with no issues. But now every few seconds it jerks forward and then back into place. Over and over again. Has this sort of thing happened to anyone else? Any tips on how to stop it?

What viewer are you using? If you are using the Bento viewer, you might have it attached to one of the ear bones in the new skeleton rather than the original head.....just a thought.

Using the latest Firestorm viewer. But the change in the hat behavior didn't correlate to any viewer update, since it behaved just fine with the same viewer about a month ago.
