I was playing single player so it's not only a server problem. I think these are two separate issues
Here is the new crash report, things haven't gotten better, I've tried opening a new world in 1.9 and it has much less problems
Don't thin it's a duplicate. The problem here is that mineshafts spawn on the edge of the mesa and go onto other biomes
I really don't have the time to play Minecraft these days, if someone else could do it I would be glad
Ok updated the drivers but the problem still is present. After some more testing I've found out that it only happens in my survival world while my redstone world which is superflat and in general less lag generating is ok. Can it be caused by disconnecting when chunks are still loading or something like that? I've attached the new crash report
Oh ok, I don't think it's a good idea but guess it's not my game
Still broken, playing in 15w38b. I should note that I'm using a fence not a full block, in the standard item elevator. It used to work at least in 15w37a
Game output
I know that, that's why I included it, but then the game stops working which is new. It's only happened in 15w37a
Yes yes, I played for 2 or three minecraft days but the lag continued
