I dont have a solution to this problem other than I also have noticed this. It is really frustrating as you might guess. Any notion on when they will be updating tekkit legends and fixing this horrible bug?
This is a bug that occurs when a RF consumer is placed in line with a energy bridge and a EU producer then hooked up to a batbox, MFE, MFSU, etc. The bug happens as soon as a kenesis pipe is connected to the RF consumer it starts generating power. This is extremely annoying as infinite power is produced and really takes away from the game experience.
