OK so gamble can't replicate it. Out of interest are you R* SC or Steam?
As I said, Only happens in multiplayer sessions, not online solo.
No idea.
I just checked and i get it too, only in freemode online. I wonder if they added it on purpose to stop people eat spamming during gun fights, ive fought people that take 5 shots before they die, im pretty sure theyre using armour or food macros.
