@Anthony Cicinelli Either the search function needs an overhaul or the bug tracker should move away from Jira because 90% of the time, searching something does not show anything for that issue even though it already exists. This causes lots of duplicates to be created, like this one.

This happens because spectating another entity only attaches your camera, not your entire character. Due to the fact that chunks are rendered in proximity to your character, when your camera moves far enough way, the rendering doesn't continue.

You can see this in action by using any mod with a Freecam mode (like Tweakeroo, for example). When you activate Freecam whilst spectating an entity, your camera will pop up where you began spectating that entity (and you'll see your character floating there, too). Deactivating Freecam puts your camera back into the entity you were spectating.

@Robert Macedolian If there was more than one, than it was an internet issue. Did not mead to multi-post.

Present as of 21w42a

Did you make sure there isn't a lava lake under the ground or nearby?

Tested and Confirmed for 1.14.4 Pre-Release 5

Renamed items still retain their usefulness. The crafting book doesn't pick up on renamed items because changing the name changes the NBT of the item and the crafting book is looking for specific (unnamed, normal) items to use.

This isn't a bug as it isn't due to the XP at all. Looking at the crash report, it appears an Enderman wandered into your return portal and glitched out.  If you can get back into your world, run the command /kill @e[type=Enderman] and that should fix it.

@Meri Diana Pigmen are different in this case, for when the lightning strikes, in that moment, the pig is despawned at the exact time a Pigman is spawned, and they always spawn with a Golden Sword.

Now this is odd... It's only when you use the "SkeletonType" or "Type" tags with the /summon command that they don't have their respective weapon. Leaving it off spawns them as if they spawned naturally.

Noticed this as well. Happened to me 3 times.Confirmed 1.9.2

Confirmed. Run in latest Spigot 1.9.2 server, got NullPointerException in console:

EDIT: Doesn't matter if the reputation is negative, positive, or zero. As long as it's there, you get the NullPointerException error.

From the start of 1.8 to 1.9. Wow. This bug has sure been overlooked.

EDIT: Just happened to me. Kinda annoying.

Happens for me too in 1.9 release. Doesn't seem to affect anything, but I think these may be causing the split-second lag spikes I kept getting.

I'm in a Creative Superflat World with a single layer of air. Trying to work on a redstone project and this is getting really annoying.
