I'm doing the sidequest where you have to collect five Hammerbird eggs. I have four and I know the fifth is in a nest on top of the dock cover/shed on the lake (the one at the tip of the roof that's just East of the first bridge into Ark, or south of the watch tower). However, no prompt appears for me to pick up the egg and I have no way to interact with it even though the egg is there. I've tried exiting the game and reloading and , I've tried sleeping, and I've tried going inside Ark and back out so the area reloads, but still no prompt.
Is there a console command I can use to get another Hammerbird egg in my inventory so I can finish this. This is really annoying.
