So, I made this plugin called Lock&Key and it has a recipe to turn a redstone block with item meta into 9 redstone dust with similar meta. However, whenever someone tries to use this recipe I get this error (upside down log - sorry). When they complete the craft they end up with regular redstone dust. I don't seem to have any problems with this recipe without PS installed.

That was fixed for 10.1.1 issue #942.

Alright, thanks.
