I could take a control point at Level 4, then top up all 3 of their supplies to 100, and then go take another control point or do a mission, and when i'm done, that control point i did before, is now in enemy hands already.
I've even helped NPCs take a control point, only to see it red again after i got done doing something else.
Is there a way to keep these control point unlocked longer? I recall having the map totally green for days on end, which is how i actually like it. This lets me do bounties easier, farm parts for crafting that is otherwise an insane grind, and even do things like hostage rescue etc, which i actually like doing despite having done them countless times already.
I have even stood there with 250 supplies for each category, and gave a control point leader the whole lot, just to see what happens, and i will still lose the control point very quickly, typically after a mission or doing anotherr control point, or even just in the White House doing some crafting and sorting through the stuff in the supply crate.
Has something changed recently, or am i doing something wrong that means i can no longer keep the map green?
