Piston can move machines

[DavidParish01]

In version 1.10 (Version shipped with FTB interactions) its is possible to move the machines with pistons. This does not crash the game but does glitch out the machine moved and any other machines act strange. Machines in inventory because invisible and in world machines flick in and out. This seems to work with any "machine"

Isn't your "problem" this mod?

which is included in FTB interactions.

"FL adds an advanced variant of the vanilla piston that can push a wide variety of blocks that the regular piston can't
(including tile entities"

Emphasis mine - machines are tile entities.
No tile entities can be moved by pistons unless a mod modifies the vanilla piston code, it is hardwired.
GTCE does not modify the vanilla piston code.
