Zandronum

everytime i start a offline skirmish mode with bots on zadronum using the wads brutal doom, the game works perfectly fine, however, after about 30 seconds the match ends. this happens every single time. i have time limit on 10 minutes and frags at 0

I'm afraid I have no way of knowing if this is a Brutal Doom issue or a Zandronum issue. If It's a Brutal Doom issue, then unfortunately Brutal Doom's development isn't housed here and probably will not see this. However, other players may be able to help if you include more info about which exact wads you're using. Also, I would try to see if you can reproduce this issue without brutal doom or with other wads.
