So roaming around the internet I've found some guides for how to create a task. But all of them were made around alpha/beta stage and they're for SP. Are those ok to use?

I have a mission on FATA where in the north I created a Taliban office building where an important meeting is being held. I want the mission to play like a normal ALiVE insurgency, with one over-arching optional task to kill this Taliban leader. Does anything special need to be done with the task marker and/or trigger initialization lines or whatever for the mission to work when persistence (and a dedicated server) is used?

Also, I don't plan on virtualizing this officer. After he is killed, will he just continue to spawn where I place him every time this mission is continued? If so, I guess I could virtualize him but I wonder then if he'll be around the area where I place him...

Not sure if making tasks like this is viable with persistence and MP in general.

It honestly wouldn't surprise me if ALiVE's persistence database didn't check for trigger conditions or task states. Obviously I'd love if you found some solution but perhaps it's just as simple as this not being possible, because ALiVE doesn't check for these things during the saving process?
