Very sorry that this is still happening.
Am currently working on resolving this issue with some other players that have encountered this issue as well.
I think I'm very close to tracking down the cause.
But this clip is extremely helpful and likely further confirms my suspitions.
If you wouldn't mind, could you trigger the bug again,
hit "Ctrl + Shift + J" (or however you open the Javascript console in your browser.)
and tell me if there are any errors mentioning "TryGetMetaData"?
(Ignore errors mentioning "Not allowed to access vertices" that's just my spaghetti bleh.)
