Hi everyone!

 

DESCRIPTION:

During the final wave of the defense mission on dwarven stronghold, starting with 15 seconds remaining until win, the game sort of froze and only proceeded 1 frame every 30 seconds or so.

REPRODUCIBILITY:

Haven't tried again.

SCREENSHOT/VIDEO:

Spoiler

 

LOG: 

Log file is too big, but the most repeated line is:

I snipped the last 10 minutes or so, here:
