I somewhat have a similar issue with my wifes game, we both play the game on PS4, when we log out of the game for the night and log back in the next evening, ALL of her inventory in her belt has been turned into bike parts lol soooo, i just take her character over to her bike strip it down and goto the workbench and combine everything and she ends up with a better bike once its all said and done. Then i remake her weapons and stuff on my character, so when all of this happens to me its a blessing, because i turn that glitch or bug into something positive, Just like you can do the same, if you messed up and it resets on you well guess what, that mess up in turn never happened and you can avoid that mess up again.
