some entities not despawning

SpinDreams, Sun Feb 02 2014, 02:58PM

I have noticed that on Vanilla refresh some entities are taking a looooong time to despawn.

I have noticed especially with embedded arrows which should take only 1 min to despawn are simply not despawning (at least longer than 30 mins) I had 2000 arrows embedded in a block from a mob grinder and they were just never despawning and simply looking at them would lower my FPS to below 10 and introduce massive lag.

I have only really noticed this with embedded arrows but think it as also happening with xp orbs (although these can be collected unlike embedded arrows). I'm going to do some testing and ill get back

Okay just checked, it seems to happen with arrows and XP, I hung around an embeded arrow and some xp orbs at spawn and threw down some dirt blocks, the dirt blocks despawned within 10 mins like they should but the arrows and xp did not (wiki says embedded arrows should despawn in 1 min). So my guess is a bug.

this is a major issue in my grinder aswell. I fixed it by destroying every block the arrows were stuck in. when they fall, they "reset" and will despawn after a minute or two. After that was done, i rebuilt the grinder so the skeletons would never see the player and thus never fire arrows. Now it works like a charm.
Dunno nuffin bout no xp orbs tho.
