Lanterns in Odd Corners

I tried to build a lantern in a corner against a two walls and the settlers placed the ladder but did not place the lantern. Anybody know why that is?

Picture for reference

I’ve found you can’t place them in corners, have to have one space between it

I’ve been able to replicate this issue. I think it is related to the following post [r144] Clipping issues with placed items but it looks like the game engine is doing the right thing by not placing the lantern there as it would cause clipping but I think the bigger issue is that it shouldn’t even allow you to place in the first place.
