Hi, im sorta new to nexuiz i like to play lan matches with my bro, i have found a really good map called switches_v1r2 and would like to play it yet i cant, i don't understand why i can only create maps that ive been on that session like when i log off i have to goto it on some1 elses server before i can play it any idea? thanks

When you download a map from a server it goes into a specific folder in the nexuiz directory which is:

nexuiz/data/dlcache

Move the map out of dlcache, and into data. You will then be able to use it when you host a game.
