as the title says. CTD when using a sticky piston.

Cannot reproduce.
This might be caused by other mods you've installed.
Please provide a crash log.

In addition, tile entities cannot be pushed by pistons.

Confirmed that @Abattoir19 is trolling (opens the exact same "crash with piston" issue to many other mods).

Issue closed.

Not being a troll, tried with only these mods installed on brand new worlds, get a ctd will try to get a crash log... its doesnt always give me one tho.

Edit: let me rephrase that i tried to use only your mod and then used a piston on a brand new world... when i do i get a ctd... i posted those on the other mods cause they do the same thing -_-

P.s. not everyone who finds a issue with your mod is a troll....

Already reported on the Forge forum.
