I was walking around a decorated city and had this crash.
I may have been sitting watching the lights for a while answering discord questions.

Here is a screenshot of the location of the crash.

This is for sure a bug. It looks like Minecraft is attempting to load a decor Tile Entity without a block being present. That's like having a chest inventory in a space where there is no chest. Safe to say, that's not good. Will fix.

Should be fixed in 11.2.1.
