which game build are you playing because most recent is different between platforms... also which camp are you going to [return to day light out side of any cave or building then] press the camp option to return to main camp
you say loading old saves doesn't fix the issue... are these old saves before you patched the game to current version?
1 you need to be all together at this time i.e, with in talking distance of each other
2 you have some suplies to eat [40 points] you can buy these from the druid grove or use food items
3 are you doing a timed quest like return to druid grove for final battle... because that quest has prerexs
