client errors

1 screenshot of each would have been enough. Anyway, client error usually happens if you reach a spot that you shouldn't be able to reach (like getting pushed into a wall). I just don't see how that would explain the error in the GM game though.

I think the add_result error is a failed attempt at adding people as friends. More people have reported problems with their friend list lately.

Might be useful if you gave us your computer specs, ping and programs that run in the background while playing CF. And if any of those errors only happen when you perform a specific action, mention that as well.
