Version 1.15.1-10.0.0.296.

Simply put, buried treasure does not appear to generate at all in a BoP world. Treasure maps turn into generic empty maps, and the /locate command fails.

I did check whether it could generate in both a normal world with BoP installed, and in a buffet Gravel Beach world, and it could do so in both cases just fine. Hoping that's relevant somehow.

I just noticed #1531 as well; presumably, these are related?

Never mind, just saw #1528.
