For our server, Z1Craft, pigmen in the nether are constantly going agressive and attacking us, when they had no reason too. we were just wandering around, not mining or attacking anything, and they all attacked us, with no in game reason too. I'm fairly certain that this is a bug, since it happens CONSTANTLY, and I tried another server, and this didn't happen. If this IS an update, please tell me so, because right now, it's practically impossible to get blaze rods, magma cream, and wither skulls.
