It looks like it did, and that was the first time I've seen that happen. Looking at the footage, I can now tell you why. There's a little ammo/cross sign on the minimap in that section, it must have the ability to repair your tank after so much time. Even though I did get a couple full repairs out of it without realizing I was still one shotted during one engagement. There are definitely not many of those areas on the map (which is huge). Normally you're stuck with your damage, and usually have to skuttle if another tank doesn't take you out first.
Thanks, good to hear!
