Warehouse not accessible except through roofed corner in 807 unstable

[raymondum]

Not sure if a a bug or a new feature but the warehouse can only be accessed when road is connected to roofed open corner. This leaves only two squares of road accessibility to warehouse. When warehouse is deleted a road tile remains behind in that corner.

Hey, thanks for the report! the tile being left behind is an oversight, I'll fix that when I get a moment.
Warehouse requiring access to the roofed tile is intended change, covered in patch notes and the #1397

It also displays appropriate warning if road isn't connected to the tower tile:

I recalled my own notes on the matter:
The road being left is on purpose, since warehouses are navigable terrain.
However, there is a more elegant method to fix this: road tile should only remain if warehouse is connected to two road tiles, and disappear if it was connected to just one.
#1415
will update this PR when I have some time, reopening to not loose track.
