My farm is 11x9 wide farm and the straw golem is trap inside with stone walls. After a while , the straw golem stop working on one side of the farm, I suspicious for it has something to do with chunk as my farm is lie separately on 4 chunks and the golem only work if they are inside 2 chunks and stop working once they pass the border of the other 2 chunks.
Also the item transfer pipe seem to not working well after I reload the game. they got stucked and I need to reconect the line every time I login.
