At many points in the game (including EVERY time I enter/exit a casino) my items are removed, for obvious reasons, but I keep stumbling across the issue of some of them not returning. Normally I save often and in numerous spots but messed up this last time. This finally got to me when my last save was hours before and I ended up losing my gobi sniper, sniper rifle, and a few other items that I use. Am I just a noob and just missing a chest somewhere that holds these items? Or did they really just not return to me on exit of the casino (Gamorrah in this case). What's really weird is that I got all my other weapons back (marksman, grenades, c4, light machine gun) but lost my most important weapons. My autosave is right when this happens so I'm screwed if this is a bug. Has this happened to anyone else and what can I do about it? Thanks

You should get them all back once you leave, so it sounds like it might be a bug. If they really are gone you can always use the console commands to get them back on pc.

Have you tried checking the physical location where the casino stores your weapons? Not sure myself but i believe they put them in a locked container somewhere.
