Idk what happened, lag or not, but I was still holstering my Thundergun and now it's not anymore in my inventory nor can I restore it?

This is what I constantly see after 5 minutes of playing

Proof of it not being in inventory nor bank

I lost it around 10 mintues ago, don't have the video of it since the game crashed afterwards and it got corrupted, I'm recovering it, so might work.
