With Gear5 Issues

So over the weekend, I was playing the game with my family. We got to a point and we left the game cause my son kept getting kicked from the game. Came back later and we can’t advance. No NPC spawns and then I noticed we only have 5 of the collectibles, which we had the majority upto that point.

Now seeing how supposedly these issues that we was having have been fixed. Are we going to have to start over?
