In the second tutorial mission you're taught how to use Heavy Bots as transports. I can load myself up into one, but anytime I try to land anywhere on the level I get the error: "Risk area! Landing impossible."

Does anyone have any idea what that's even referring to? Or how to workaround it? Due to how the campaign is laid out I can't just bypass the level.

Kept fiddling about and it turns out that's just a horribly labeled message for "You are too high up to land." Apparently you must go to minimum altitude before you can try landing. Anyway, not a problem anymore.

EDIT: Could someone post a message here so I can close this question?
