Is it just me, or do the loaders from this mod have zero snapping logic? When you put them down, they don't react at all to what's around them, they just get placed and you have to manually rotate the loader if you want it to insert into anything.
There is an error on line 61 of control.lua which causes this behavior. I have made a pull request to the author's git to expedite.
