Playing Celesta I had tier 2 and 3 units stuck at spawn. They were trapped by the mining units at main base area. I was playing bottom position on Art/PvP Map. May have to do with location rally point?
Ahh yes, I've seen that before. Thanks for the screenshot.
It looks like those two purifiers were both trying to path in between the base and the coin well at the same time and wedging each other out. We will need some kind of coordination between units to solve this.
