What happens if I add a unit in a unit group to the same unit group again?

[Marsmallos]

The question is pretty self-explanatory. If I add unit A to the unit group UNITGROUP, and later add unit A to the unit group UNITGROUP again, and then use "pick every unit in UNITGROUP and do actions", will unit A be picked twice (ie the game has saved it to UNITGROUP twice)? Or will the game see it as the same unit and not add unit A to UNITGROUP again if it already has been added previously?

The unit won't be added again.

It's true what maker said,however,adding unit more than once to same unit group could cause errors,careful with that.

That's not true. Using a trigger to periodically pause a unit won't cause errors. For each action Warcraft 3 takes, before the actual action, there is a boolean that will handle the is a unit x/is not a unit x statement.
So, before the PauseUnit() action, it will firstly check if that unit is already paused, before the GroupAddUnit() action, it will firstly check if that unit is in the unit group you are adding it, before the ShowUnit() action, it will check if that unit is already hidden and so on. If such comparisons didn't exist, then bugs would come up.

I was wrong then,though i've heard few times that it could cause bugs. Sorry for my wrong statement.
