I'm playing through Steam. I do have a wireless connection, however this is not a general error. It only happens in one location in the game.
Every time I try to get to Giant's Scar on Io I get kicked out with a Weasel error.
This ONLY happens when trying to get to Giant's Scar, I have been to the tower, Mars, and even landed at The Rupture on Io just fine. I tried to sparrow to Giant's Scar and again got the error.
