Recently I discovered that dropping a platform from the Root Template and throwing a ladder on it doesn't allow characters to climb onto the platform unless there are stairs/ramps leading up to it, as well. Is this really the case or am I missing something? Even painting on the AI doesn't work. I had several wooden platforms in an area that were meant to be accessible by ladder, but after rendering the AI the platform remained red on the grid. As soon as I threw a staircase on the other side, the platform was now walkable.
I know there are GM Mode levels in-game that allow this, so why I am not able to do so?
