harvester seemed to fall in a dead loop

After it happened, I used a external map editor to remove the harvester block so I can enter the map again. A screenshot after the block had been removed: (replaced to an iron block) MCPC's stack trace of the problematic thread:

Although the map is played under MCPC, the problem still present after running the map in singleplayer.
