I was playing Echelon yesterday and I’ve seen a bug:
The other team got the Double Thralls and both of them walked in our first sentry room. The problem is: they completely ignored the sentry and kept walking to the second one, even taking a lot of damage of our sentry and turrets, they were not even shooting at us, what made killing them very easy. The push will probably destroy our sentry, but did no damage at all. Our first sentry was 100 health, before, during and after all of that.
I don’t have a video or a screenshot of this happening, though. Sorry about that.
