I don't know how but I sometimes run into a bug at the repair facility for each faction when I order an injured vehicle to repair and it moves on the repair pad but isn't centered and is partially covered by the building graphic. The vehicle is unable to repair and selling and rebuilding in that spot doesn't fix the issue, the only work around I saw was to build the repair pad far away from the bugged spots to heal the vehicle.

Also for the map editor, are the wolverine and Gatling tank suppose to have invisible models once placed on the map?
