Even if there weren't any beds available, they should seek shelter inside a house instead of staying outside at night...
Still an issue in 1.14.3.
Got this bug recently in 1.13.2.
While in the Nether, two Skeletons were aiming at me, one missed and hit the other Skeleton, so I left them to fight each other and watched them from a little further away.
While fighting each other, one Skeleton hit a nearby Pigman. The Pigmen killed the Skeleton that hit them, then they all targeted the second one. Thus far, I didn't notice any change in behavior from the Pigmen near me. When the Pigmen killed the second Skeleton though, then all the Pigmen near me became aggressive towards me.
So, apparently, they aren't automatically agressive towards the player once they kill the mob that hit them, they just turn aggressive towards the nearest mob?
Hope it helps. 😃
I also have this bug. I created my world in 1.12.2, updated to 1.13, then 1.13.1 then 1.13.2, never used any snapshots or pre-releases. So I guess 1.13.2 could be added to the affected versions?
I started building my farm after updating to 1.13. I noticed while building it that no wither skeletons or blazes were spawning anywhere though (in my farm in progress or in the surrounding fortress).
I heard this bug could be related to switching your world to peaceful, though I've only did it twice, once when I was still in 1.12.2 and the second time was after noticing the bug, so I'm not sure if it is accurate or relevant. Thought I'd mention it, though.
Please fix this, I can't get any more beacons and it's annoying. 😞
Thanks.
Still an issue in 1.14.4
