Pigmen still lag like hell and instead of crashing that option keeps the server on but times you out instead, doesn't happen anywhere but when pigmen are angry... that other topic is just crashing so not sure how this is resolved and a duplicate..
Here's the Crash Report
That does not seem to be the problem, this happens in the nether and apparently in The End and not in the overworld, only happens to pigmen and seem endermen when they get agro it causes insane lag to the point the server times the player out, this never use to happen and i just did a test with the snapshots, 15w47c it's all fine but the moment i go to 15w49b it begins to cause lag and same happens for all snapshots above and before you say it's something wrong with the server or pc every single member gets this problem.
I keep getting links from you all which does not seem to go anywhere near the issue to the point you even put "resolved duplicate" this wasn't even resolved and it for sure isn't a duplicate.... pretty messed up.
