I discovered this plains village with a lava pool that generates in the middle of the shop area. What is the worst about the lava pool is that THREE villagers, a cat, AND a golem just so happened to spawn in the lava pool. This can be reproduced on seed 10114363738 at the coordinates of -264, 74, -269. If you teleport there, wait for the world to load on your escape screen, and then quickly look to the lava pool, you will see all the mobs immediately burning up in the lava with no way to save them. I haven't seen any other seeds where this happens, but I'm sure there are and they just haven't been discovered yet.

Either villagers and other mobs need to not spawn in lava pools, or lava pools need to not spawn in villages at all to prevent this from happening.
