None of these worked. Only time passing apparently solved it. They said they’d contact me if it happened again, but I figure I should report it anyway. I was not able to replicate this on mobile using my account and a non-BC alternate account.
The user has the iPhone 6s with the latest Roblox Mobile version and uses iOS 12.1.2.
Apparently the bug is happening right now (4:17 PM ET) again for the player, I think it may be server-related, as the DevForum and Roblox are giving me errors/running slow at this time.
