a create compatibility for this mod would be very neet

What kind of compatibility are you looking for? I've tested the mod with Create and everything seems to work as you'd expect.

I may fix this in the next patch.

Same for me, A-OK. One thing that bothers me though is 1 pixel off for create bearings:

cart assemblers from create can't be put on any rails of this mod
