As of ~1 day ago, R6 will randomly load despite avatar settings. This seems to happen sporadically on VIP servers and Studio play solo sessions. You can attempt to reproduce this by joining an empty VIP server. When this occurs (especially in Studio) loading the game takes much longer and Studio will occasionally freeze for 3 seconds. I first started getting this bug via. Studio yesterday several times in a row and got reports of it in Pet Simulator shortly after. The Roblox website was being exceptionally slow during this time too. There were no console errors.

Edit: This is still happening. Me and @silky_dev are getting lots of reports of it.
