I appreciate the system trying to be smart and make nice curves joining sections of roads around buildings, but it just becomes really annoying when you can’t just force it one tile up to a corner then one tile at 90 degrees to join two sections of road without deleting huge sections and re-doing the whole thing.
Which leads me on to my next issue. Clearing a road, even selecting in a marquee the smallest section will highlight a long section to be deleted. Most times I just want to delete a few tiles not miles of the stuff.
In short placement and removal of road should be by the same method. Click and drag. Also allow a minimum of one tile at a time to be placed/removed (basically a double click on the same tile)
