I'd like to point out, that at least for me, the Stairs in this mod do not work as Stairs i.e. I cannot climb/walk over them, but instead have to jetpack. I DID try flipping them to see if I had put them in upside down, and although one end is easier than the other, it's still not climbable.

i have crashed when ever these blocks contact other modded blocks from any other mod.

getting obsolete method / type warnings on this mod when loading, looks like the mod may break soon if they remove the backward compatibility in any update. Might want to skim over the mod specs and run a find/replace and reupload.

Thanks PhoenixX, I'll check it out!

Seems as though there is a problem with the view when in first person. For me, my character is standing up in the seat and is blocking the view.
