Okay so I need help guys, with trying to see what the issue is with this.I've been making a mechanism with redstone, it uses a clock, and there are sticky pistons connected to the clock. Anway - sticky pistons appear to PUSH the gravel, however, they won't pull it back. Without a torch connected, the piston is still released.I tried it on single player and everything works fine so it's just an EMC (SMP2 issue). It's also just gravel (not sure about sand), no other block.Is this something to do with the piston glitching after 1.3 - if so, I thought this was fixed? Help me, please! D: Thanks in advance.
