For some reason, often when I explore the world on servers, the world suddenly glitches out, blocks often only show 1 side, or are completely invisible, and often it looks like 2 biomes colliding. This happens even in chunks that had loaded normally previously. When entering the messed up chunks, major lag happens, and when I leave the server to reload MC, MC crashes completely. Anyone know why it's happening or how to fix?

Crash report is below.

I got banned for no reason by one of your helpers.
Can I please be unbanned?

UGH! It's no longer down for maintainence, but so many people are joining that the authentication crashed again! IT'S FRUSTRATING TO SEE MANY OTHER PLAYERS GET ON WHILE YOU'RE STUCK OFFLINE!

i like signaturecraft. its kool

One of the best ways to pvp on most servers is potions. Go on the minecraft wiki to see brewing recipes. Go kill some blazes! Damage potions and poison potions do more good than you may think. Once the potions have done their job spam your sword or bow at the enemy to finish him off. The bow and arrows work great as if the enemy is close you can spam arrows knocking them back making it hard for them to hit you (punch II works great) and it damages their armor and health very quickly.
