Battleships can sail on land. Can't place metal extractors next to cliffs/crevasses. Quite severe performance issues after a certain point
1st one is not technically true; it's a display error, if you look on the pathing map water is there, and that bug has been there since alpha and they're working on it. Same with the 2nd one. 3rd one is obvious due to lack of unit restriction and optimisations right now.
