The function Command() corrupts the serverside nextmap variable.
I came up with it when working on a !nextmap script. After I implemented a !votemap <map> command it did not work any longer. I changed the Command('/nextmap') to Command('/map <map>'). The map changes, but when I use !nextmap it always jumps back to one map. (The second in the mapslist)
Using it as admin works /:
I have absolutely no idea why, I hope you understand what I wrote
