Was going through some old gameplay footage... came across this bug from this video. Quite amusing stuff.
Wasn't it changed though because the pathfinding completely broke on them? It was all too easy to get your commander stuck on one and impossible to unstick him. I hope they'll change them back, but only once that's fixed as it rendered moons unplayable.
And? So long as the game hasn't been released I don't see why that's a bad thing. You'd rather moons played like desert and lava with everything getting stuck?
