Whenever the script tries to "tunnel solve", it basically just floods the client with errors and you have to force close the client.
Other than that, it works fine. But it seems to need to tunnel solve often, so yea.
edit: sometimes it will bank before finishing all kills, i'll come back to the client frozen with all brothers killed and regeared, so it seems to be an issue if all of the brothers are killed and it tries to come back to that
hopefully that helps determine the problem
