In the other campaign is bugged but not that much.
P.S
Video related it happened 3 times in the same game, The bots didn’t throw it back, the pack of explosives just didn’t explode.
Interesting. Did it not explode or just not kill anyone when it did?
The reason that I ask is that I’ve been having issues with FRAG grenades landing in the middle of groups in Berlin, Normandy, and Tunisia that I actually see it go off, but it either gets no kills or only kills one or two.
I notice that sometimes they simply don’t explode and some other times they explode but whit 0 damage for the enemy.
That is true, Forlorn, it should be posted on the bug page, but it`s also good to find out if the problem is happening to other players as well. As for me, this problem is happening quite a lot, so I was pleased to see this thread put up 
I think maybe what the problem is, is that, RenoPro, was shot dead just a second after the det pack left his hand, canceling out the explosive all together, even though we could see it landing in the room and at the enemies feet. To be fair to the player, though, that det pack would have still been on it’s way to it’s target in real life, so this does need to be looked at for sure.
