Depends on what areas you do maps in. If its a grid that has the unusually high mountains and sheer rock walls. Just throw em all away. Unfortunately our grid is surrounded by those islands. Even the polar ones we have done were all fucked but for different reasons.
Hard to believe you have such a high ratio of maps that are possible. Lucky you I guess
Could you let me know which islands you were playing around?
Edit: Okay, we've identified an edge case where it may have appeared in a location that wouldn't have been viable, it's being fixed now but won't be retroactive (i.e old maps won't be fixed). It'll still be good to get any grid locations where you find yourself having issues and we'll investigate from there.
