You need to Chapter Select certain saves, not continue. This is what is causing, the confusion of saves loading in the wrong place. Because you keep resigning saves & adding with the saves in your console ones. Example: resigning save 2, then doing the trophy, then doing save 4 & pressing continue. You'll be wherever you were last time. I've checked every file, & all of the saves, like 3 separate times. Each one loads in their correct places.
Heres an editorial list of everything:
1) For emergencies only - FIXED twice
2) Artifacts Base Game - NO FIX / Just a glitch, some collectibles despawn -
3) Scavengers - FIXED - it'll only work when you have all of the other collectibles done, to ensure you get this with a save, use a file that has a collectible you haven't gotten. Specifically with a certain collective type related to unlocking Scavenger then use the save get the other collectible & you'll get it, b/c this checks each profile & then unlocks.
4) That's all I've got (All Ellies Jokes) - FIXED - this was b/c people loaded up the wrong saves.
