Delta Force does this too but it doesn't happen as often I assume, and unfortunately, it always benefits content creators more often since they have a larger following and pull.
A friend of ours had this happen as well. He posted the screenshot of his returned items in our Discord and said he has a newfound respect for the game. Things like this are what keep good players coming back and draw new players in. Good job, Embark!
Delta force has this, (game full of cheaters) & it rarely actually works 500+ raids & only 2 returned loadouts.
I'm sure some hacks will still go undetected.
Just so you know, this also happens in The Finals, where your rank gets adjusted to reflect a new total based on what you lost from the match where cheaters affected the outcome. W Embark.
