Yes this was from the shop, at the time just before posting the previous message.
Someone had traded me $33600 for 10 crates, I would buy them, and trade them back and give the crates. Had done it many times without issue.
This time, as I was in the menu buying the crates using the option to buy multiples at the same time, as I hit enter to buy I was killed buy explosion/jihad in game, the money disappeared and the crates didn't arrive in inventory.
Neither crates or money have appeared since.
I have done successful trades since this happened as well
