I also see this in the launcher log

Java hotspot (yml) 64-bit server VM warning: using incremental cms is depreciated and will likely be removed in a future release.

We are using launcher 1.6.48 and shortly after the skeleton ai froze the game crashed. We recreated a new world and received error in launcher saying: can't keep up. Did the system change, or is the server over loaded? Running 4366's behind, skipping 87 ticks.

The screen is also flashing many block skins when we walk.

Well we were in default gamerules with a new world. We just forced mob griefing to false just in case and zombies will not pick up items. We are also noticing skeletons spawning with no AI. We cannot kill these skeletons and they do not move.

However the villagers are picking up potatos

Also the pigmen and skeletons will not pickup armor too.

We did these tests on normal difficulty. I just tried changing to hard and easy. The difficulty does not fix the issue. We are spawning them with spawn eggs not a command. We also tried natural spawned zombies at night. Nothing I can do will make zombies pickup or equip any item I throw on the floor at them.
