0007904: Cannot traverse ramps across tree roots
During terrain generation, the game appears to discard ramps which are bordered entirely by tree tiles, and attempting to traverse a ramp along a root tile fails (you simply don't move at all). It would seem that the ramp logic is not treating root tiles as walls, even though they turn into walls when their tree is cut down.
No tags attached.

Can confirm this. I'm surprised it hasn't been reported earlier, but I guess I (as everyone else must have) assumed it might be working as intended. I'm not sure it makes that much sense, though.
