I tested out the plugin, and it worked fine on dustbowl for me. I added a command so you can change the time left to a certain time if you want. Also, you can use negative numbers for the addtime command to remove time, but if you go below the time left, the game will glitch and get stuck at 0 seconds. I might make a fix for this later on to prevent it from happening. You can fix this glitch though by setting the time to 1 using sm_settime.
