User can build buildings half out of the map.

This is still happening. I just crossed over with tanks to the enemy location and just built there a silo, far from my base.

Also, when selling a building it should leave a soldier behind, but guess you not reached the making foot units yet

Another thing. Created a weapons factory on the spot I builded a silo (top left corner of map) and builded some tanks. They just kept wanting to move to the right side of the map after leaving factory

When constructions are destroyed (this excludes turrets I think) they leave some troopers behind, too. This should be moved to a separate issue, though.

Having checked the game I can add that we can only build close to each building, as in white building zone should touch a already builded one, and the first black fog area can be used for building
