The problem is that you have to bind changemap_to_current_random_sector. The next problem is that you can't bind it anymore. changemap should work fine tho.
The other problem too tho is that command is glitchy even when used properly. Karoks for some reason can't use it more than 20x before the game crashes, possibly due to a bug in the character code within the game. Also, I've noticed on my fast computer, I can use the command 10x more times than on my slower computer before vindi crashes. So again, probably something to do with the game itself.
Hm, thanks for the help. Maddoggy is right, changemap is pretty glitchy and for me it only works about half the time. My main bot acc is a lann so I shouldn't have any character issues, and I run Vindi on the absolute lowest settings when I hack or bot. I guess, unless there is a way to complete the mission and kill Silberin without getting banned, there's no way of creating a pure mining bot for Silent Blade. I guess I'll try creating an AutoIt bot that mines the first floor, skips to the boss stage and delays for a good time before killing...
