Don't know where else to report bugs, so I'll say it here. I found a freeze using one of the new runes, the one that causes the "explosions". When defeating an enemy with extreme speed, with an enemy behind them, the "explosion" damage will apply, but probably because they're being damaged twice at once by the extreme speed and the "explosion" it causes the game to hang and be unrecoverable.
Here's a screenshot of how it got stuck.
