Thanks for the clarification.
I have found a workaround for a possible plugin. I just need to make it.
The sudo code would be something like
Code:
If map is cp_ and time remaining is 1:00 ( set mp_timelimit "" and mp_maxrounds to total-rounds-played+1)
That way you switch to using the in game timer instead and will play until the timer you see on the HUD ends instead of the separate map timer.
