Hey, I just encountered a bug caused by this mod, where a tree just on the edge of a tile can wind up interrupting train tracks... without interrupting or blocking the train tracks.

Yeah, this is a side effect of the mod. I've had this report before, and I don't really think there's much of a workaround other than removing the trees with something like the deconstruction planner with filtering active.

I was wondering if you could add a special case that expands rail tile collision boxes to compensate - since you don't "run into" them anyway I don't see this causing any major issues unless you expand far enough into neighboring tiles to prevent building things ADJACENT to rail tiles (signals for example).

But it's not a huge deal, I even got a bit of a laugh when my train proceeded to phase right through the tree ;p I just figured I should mention it since I didn't see any other threads about it.
