Hello!
I never seen this bug if it’s really happening you should report it to Studio Bugs so Roblox can fix that,
Also this is a very rare bug, I think because lot of people never has this bug,like me
If you report this you will not be instantly aswered, you need wait like me I reported a Website bug and still no reply,
So yea report this so it can be fixed
That’s all byee!
