This shbfhbjfsdajdsa (what a mouth full) guy used a shield, then quit, and the shield stayed up. It doesn't really affect the game, and I don't think that the shield was actually still active, but it does look a bit silly. It was turn 4 by the time I screen-caped it, but the shield had been up since the first turn. The point is, if you quit with a shield (I think) it will stay in the game until the game ends.
I have had this happen. It doesn't do anything if you shoot it when it happened in a game I was in. I tried taking cover in it.
Yeah I thought as much, even wasted a few turns shooting it to make sure. I guess it's really more of an aesthetic thing that could be patched up then.
