Well, I know what you shouldn´t do... Dont make 2 threads about it.
If you lost 800 pistols due some weird bug, I think you need to talk to Kingsam or so.... Tough I dont think you will get them back, its worth trying Ithink.
In reality, there are four possibilities
1) You sold them
2) You didn't buy them in the first place
3) You used them
4) Someone else knows your password and used them.
