I have tested this problem multiple times, in many different scenarios. Well, actually, let me explain my problem. If I place any form of redstone current to a redstone engine, it does not do anything or make any movement. I have tested this on a 1.3.9 AND 1.3.13 server, and it does not work on either. I have also tested this in singleplayer, both versions, and still nothing. I even tried multiple ways of applying a redstone current to the redstone engine. Please help me! I don't know if it is a bug, glitch or what. Thank you!
