So while Nemesis has been living up to their name and make me regret my life choices (and especially my force selection), I had an unexpected interaction between my Mk19 Humvee and a building.
Previously, the wild spread of the Mk19 has caused more than one friendly-fire incident (indeed, there was one case this very match), but I've been having passable success rolling them out more to spray the targets for 15 seconds with a 15 second pause. In this case I was a bit nervous of the road, so I put in a 10-second pause, assuming that the Humvee would reverse away and stop firing when it had moved behind the building.
What actually happened is that it proceeded to fire through the building, with the grenades continuing to hit the target.
Is this an unexpected interaction of some sort, from building proximity and grenades that won't go off at short range? Or is it just a bug?
