Invisibility

So I was on Money the other day and THIS glitch happened.

I saw it once before this, but thought it would go away and I would never see it again, however it happened again that same round with another player. The models no longer show up and it is just the gun.

It happened earlier in the match when someone's body was standing in place behind a burnt out tank, but they were shooting me from a repair pad about 30 feet away.

 

I sometimes get this when I alt tab out too long.

 

That's a source engine bug, happens on all source engine games I've played.
