I was playing a practice match with bots and one turn on the blast phase all the animations played but no damage was dealt and it wouldn't progress any farther. The timer still kept ticking up and I could pan the camera but the match was essentially frozen.
One bot was dead and the match was tied 3 kills to 3 kills on the 14th turn, not sure if that's important just getting all the details.
After a couple minutes it allowed me to plan my turn again, but movement never happened and damage didn't apply from the previous turn despite my ability going on cooldown. The next turn ran fine, but one of my teammates died and the match should have ended. Instead it stopped again just after movement. It took another couple minutes for the match to end.
