I'm using OpenBlocks with Morph and when I'm morhped as a bat.

With the setup above from the bottom elevator I can go up to the top, but form the top elevator and go down to the bottom.

The mod versions are:
OpenBlocks-1.7.10-1.3-snapshot-502
OpenModsLib-1.7.10-0.6-snapshot-264

P.S. I'm also using OpenPeripheralAddons, OpenPeripheralCore, and OpenPeripheralIntegration, don't know if that's relevant.

Well, it's somehow intended: you need two spaces for normal player, otherwise he would suffocate. Not bug in strict sense (it can't happen without morph) but I guess I can implement it.

Thanks, I see the logic in requiring two block spaces above the elevator, but in terms of inter-mod compatibility this would be incredibly helpful.
