dont do that kind of trigger, it'll make it lag a bit more. Instead try running the victory trigger every time they score a point.
EX:
Events:Unit enters region
Conditions
Entering unit has (flag) equal to true.
Actions
Set team 1 points = team 1 points + 1
Run Victory Trigger
(this condition is boolean, but you select unit has item under it).
(Victory Trigger)
Events
(none)
Conditions
None
Action:
If (All Conditions are True) then do (Then Actions) else do (Else Actions)
If - Conditions
Team1Score Equal to 3
Then - Actions
Game - Victory Player X (Red) (Show dialogs, Show scores)
Else - Actions
If (All Conditions are True) then do (Then Actions) else do (Else Actions)
If - Conditions
Team2Score Equal to 3
Then - Actions
Game - Victory Player Y (Red) (Show dialogs, Show scores)
Else - Actions
