I get the same issue but I've found a temporary fix--to close the first bot window. For some reason, the script starts on the second bot, not the first.
But now I have a bigger issue. When I run mirror mode, I'm stuck on searching for osrs client to attach to...
Im on a Mac. I've looked at all the other topics regarding this issue, but none seem to resolve this problem. Is there anything else you can recommend? There are a few nuances with this problem as I've been playing around to see why its happening. If you want, I can give you more information on Skype.
I just really want to fix this, and I know many others are having the same issue.
