Just played a game on a system with two metal planets and unit pathing was basically non existent. Units got stuck on every corner possible. They weren't able to pass over bridges/ramps so it was almost impossible to attack enemy by land. Don't know if that was a map specific problem but it was very bad. Attack command did not work at all. Only move command worked marginably.
Replay ID: 12907659070502731013, System: Cerveza System, 2 metal planets, 2 gas giants, 2 moons. Planet Estrella Mahou was problematic. Problems started around 12-15 minutes in to game. Could not get critical mass of units enmassed to attack on land since they got stuck everywhere possible.
