rftools 6.0.1, ftb beyond 1.8.0

moving a sequencer causing a game crash. after starting the game again, the sequencer is moved correctly.
(I want to use this for an multiple endergenic generator, i figured out, at game start some generator setups don't work until the one of the sequencers are replaced. at the moment i realise this with block breaker and placer from actually additions and a xnet setting, but with the builder i could to it for all 25 stacked endergenerators i have at once)

I need more info. What are you doing exactly?

i made a space chamber around a line of 5 sequencers. so that 5 blocks are within the spacechamber. then move it with a builder. moving stone or stairs is working as it should. but triing it with sequencers the game is crashing
