In that case, I would suggest moving more slowly to allow worldgen to catch up.
I'm not sure if this is the right place for a bug report, but- RotaryCraft latest version (currently V29g) The shaft power bus is "making up" more devices than it is connected to. I have it connected to 61 fans, but when i look at the power bus controller it says power is being split between 13712 devices (and climbing). I've attached screenshots. if you need my logs let me know.
Are chunks in the region being constantly unloaded and reloaded?
That was never an option - the seed is randomly assigned every time it is generated, and always has been.
