A different but similar issue is happening in the 1.5 pre where I can just walk into the chest I'm going to post a scene shot of me doing this. The method I took to achieve this is as follows
Place two double chests on top of one another.
Place a sign one the front of the two chests.
Place a dog at a angle
walk into sign side keeping crossbar on the dog
Result is shown by screenshot
Any one see a trend for ubuntu users for these things?
I agree that this is still happening in 1.5 pre
Edit: and with server running on Ubuntu LTS and played on a windows vista computer
I was just watching a calf I breaded and it grew then instantly died (no xp) and turned into uncooked steak. Ill try to get a screen recording once the official version is released because I can't seem to get snapshots working in ubuntu even with the wiki.
