Can confirm that this is an issue with specifics from MC-158933 https://bugs.mojang.com/browse/MC-158933
The main issue seems to be with paintings larger than 2x2 in any space, when the invulnerability data is merged or modified the painting will break and pop off the wall
Confirmed for MC 1.14.1 Release
So this is intended? That's ridiculous! How are players meant to share links now 😞
I can confirm that this happens, I just hope someone update the Confirmation Status and get this fixed!
