MCPE 1.1.0.55 has this issue for iOS. Strange I never found this entry even after searching the bugs before posting mine earlier this morning.
EDIT: Forgot to add that it happens when opening any Chest. I haven't tested in creative mode so that might be working fine.
I have this same error/issue on the iOS version 1.1.0 on an iPhone 6+ version 10.2.1. I'm submitting another ticket so hopefully it's not considered a "duplicate" even though they're on separate OS's
Matt, I have the most recent version installed. I actually waited through three updates before complaining. I'll test classic but honestly I don't want to memorize recipes which is one gripe I have about the desktop version. I'm willing to admit that I'm lazy. 😛 Plus one thing I'll never understand is why each GUI has different bugs. It "should" just be a skin/overlay as far as I understand. Meh. I'm not a programmer so...
