Woohoo I can't wait until my sugarcanefarm works again
Another screenshot of 30w01b - exactly this setup did bug the piston out everytime it pushed the sugarcane
Yeah at first, I also only got the bug in N/S direction because I powered it different
It can also happen in East / West direction - it's about how you power it: http://i.imgur.com/Jh6gF.png
It's the same thing but I think this one has better pictures and description - This bug is really annoying when making sugar cane farms.
Seems like it still is a Problem in 1.9
