I was just in a game on Ammo Mule where we had the enemy ball down, close to winning. We had all our base turrets built, and no enemy bots were even getting close to our base. I died at some point, and when I respawned I saw 2 gremlins take down our moneyball. They bypassed everything and took out ball down on their own. In the current state of the game where a single ball drop usually determines the winner, it seems very wrong that gremlins can bypass everything to bring it down like that
They typically target targets and pros first. I've never seen them directly attack a moneyball. Maybe its just a little glitch.
I have seen this happen, it is due to the gremlins not being able to find a pro on the low ground of a map so they go for the next target which is the ball. As an assassin if you get lucky with this you can find a spot to hit the ball a few times after the gremlins take it down and its game over if your team can hold.
