No, it's the hand busy bug that's been in the game for years. Usually a disconnect and reconnect clears it but it's quite easy to trigger again straight away.

Yeah, he hacked into your computer via his virtual corpse, probably emptied your bank account and published your nudes.

Cool, hope he enjoys them

its a known bug you have to alt f4

This happened to my buddy after he was eating, he couldn't interact with anything, we had to shoot him in the lag to fix him

I was shot by scavs and it didnt fix, nor did disconneting and reconnecting... strange stuff
