Naturally I stashed it away in my "I'm a weapon hoarder" crate at sanctuary and went on with business.
Eventually I was able to buy a stack of more than just a couple rounds for it at atom cats. So the next time I came home to sanctuary I tried to pull it from my toy box, only to discover it wasn't there. After frantically checking all my crates just to be sure, I started going back through my saves to see when it disappeared. Turned out it disappeared roughly 6 hours, several long quests, and a whole fortress built earlier somewhere between 2 days 9 hours 15 minutes play time and 2 days 10 hours and 4 minutes.
Further investigation revealed to me that my big boy also disappeared from that same trunk about 10 hours previous.
Of course Ronnie shaw won't sell me a new one either.
Has anyone had this happen? Maybe find a work around or a way to restore them?
No I can't use console commands, I'm on ps4
