After taking a Island, i have come across some buildings which i cannot enter or activate.
One such is located on the small Island to the SE next to Isolus.
The Building does not show up Marked on the Map, I can drive to it, but can not use the activation Pad.
Have also come across some Drones laying in a field, but nothing to activate or get Blue Prints for them.
Enough time spent watching the screen, while waiting on the SLOW BOAT bringing supplies.(would like to see a time control speed up/down added).
But Running around a Island looking for an unmarked locationonly adds more frustration to the game.
