Noticed when I tried to use treated wood ladders in conjunction with treated wood trapdoors from Engineer's Doors. Vanilla trapdoors let you climb them as if they were ladders when they are touching a vanilla ladder, and Engineer's Doors does the same thing, but with modded ladders as well. I don't know if it would be easier to fix it in your mod, or for Engineer's Doors to add compatibility with your ladders.

Hi, quickly double checked. It's a bounding box issue (the vanilla ladder has a wider BB, so you virtually bump your head on the trap door, also happens with vanilla trap doors). Will be fixed in v1.0.1b2. Thanks for telling.

Ok, pushed to the develop branch. That was luckily an easy one to fix ;)

v1.0.1-b2 released.
