Host, playing alone

I’ve already put 20 hours into playing this character, both in my own world and by joining friends. But now i find that my own saved world is bugged, or something, the farm mission is completed but still showing on my map, and the quest items are invisible and still pickable.

As for enemy spawning, I was having fun farming out enemies at the airbase, but now only a single tank spawns as before there were runners, harvesters and even drones but now nothing spawns there, unless this is intentional, but then how was i able to kill multiple harvesters before?

Me and my son have played multiplayer twice (Deleted our save data and stated again); on XB.

Both times, when i have gone to play my game solo, it has been a similar situation to yours.
Can`t get mission tracking information. Missing items, etc…
