Me and a couple of friends have been playing on a server (with keepinventory set to true), and recently I got blown up by a creeper. When I respawned my inventory didn't load for a solid minute, and when it did I was immediately kicked from the server. Every consecutive time afterwards when my inventory loads, it kicks me right after. If we change the world it seems to work fine though. And we also deleted my Player DAT file from the world, and no bueno.

Slight update: we deleted EVERY trace of my player data from the world, all achievements, playerdata, etc, and it seems to have fixed it, but the next time I died it immediately started doing the same inventory glitch.

Slighter update: one of my friends that was also playing, didnt really die yet, so recently they had died in the game I guess to Any mob, and it is now kicking them upon inventory loading or after a little while of walking around.

the file for the world, a friend said apparently the chunks got corrupted, but i have no idea what by still???:
