Confirmed for 1.15.1.
I guess it could be, yes.
Can confirm on 1.14.2.
Can confirm on 1.14.2 Pre-Release 3. Here's the crash report:
Upgraded world from 1.14.1 to 1.14.2 Pre-Release 3 via --forceUpgrade --eraseCache. Put the files back into hosting and turned the server on.
Was flying and teleporting around just to give it another pass and make sure everything was OK, then the crash happened.
PS: Sorry for double post. Had page-loading issues.
I am unaware if this behavior existed before 1.14 as I've created this design after I updated my server to 1.14.
I can confirm this bug. In my game (multiplayer server) the dragon does not appear to be coming down from a certain height. It just wanders around that height.
I'm not sure if this is related, but on my server there are chunks that keeps bugging still (see attached screenshot). I've upgraded the chunks to 1.14 pre-release 5 with --forceUpgrade --eraseCache:
Haven't found a way to reproduce it other than going far enough to unload the chunk and randomly come back with the lights not working.
It appears that this affects hostile mobs as well while they are trying to follow you in water
I'm the data pack developer, this report was sent to me. It could be a data pack issue, since it freezes the villager's AI to apply some changes – maybe something went wrong on the unfreeze step.
I'm unaware of the freezing issue and unable to reproduce. If you could talk to me on Discord at ScorchedPsyche#8435, we can try to pinpoint if this is a data pack issue.
