Ok, let me explain what I know about the issues with paintings.

Paintings are an entity, so I anything they are treated similarly to mobs. I you plate a stack on your walls, minerealms anti-lag mob slaughter machine probably comes and evaporates them... So, not much we can do.

Additionally, even if you only logged out, entities like animals are saved to the chunk when it's deloaded, I'm not sure if this holds true for paintings, but I would assume so. There are issues with this code which can mobs to appear in different places. If we apply this to paintings, they could appear in mid air, and because no ordinary reason destroyed it, it didn't drop a block.

So not much we can do? I am under the assumption that Intelli wrote the coding for the mob thing. So, he should be able to change it...
