i've captured (killed all NPCs) a lvl3 outpost, but i didn't got credit for it! the outpost is still red, but my allies standing around and chatting... no takeover and no supplyroom unlock! these bugs are kinda frustrating
Happened to me once (on a normal outpost), found a 'stuck' enemy on the edge that wasn't triggering the friendly npc. Have a good search, high, low and all around in case you got one stuck/hiding somewhere.
