Sounds like MC-138108.

Could be related. To the reporter: Is the location you tp to over ocean for you?

Why is the duplicate of MC-138108
my problem is not the same as the other. The difference is that the other problem is that the liquids generated in the unloaded chunks while mine is describing the liquids and the entities in loaded chunks in the debug world.
