@shadeofblue I'm experiencing this quiet a lot on the latest 0.12.0-RC's . It appears to happen when either your connection is broken and also at other times i'm not completely sure. The yapapi agreement doesn't get broken up when this error happens, so essentially the script is just not working until you restart it.
