My mates and I were searching for maps to play and we ended up stumbling on this one, pretty neat map might I add, we then started exploring the map to see if we could find npcs to take quests from, we found the dudes that live underground.
We do the first quest (the one where we need to go to Dublin to find a note) and when we got do the second one (the one where we go to the anti-air defense fort), we can't pick up the quest items, they spawn for all of us but none of us can pick them up, so we head to the brewery to clear the beacon and get the boxes of beer, and we can't pick them up either, we gave up on quests and we're just expanding our base for now, devs, please fix.

I've made this new thread because apparently this glitch has been around for a while and hasn't been fixed yet.
