I was able to record some instances of the sound issues and freezes that I've been having.
The pattern is always the same: at some point during gameplay, the sound begins to do strange things- sometimes it repeats the same sounds over and over; sometimes all sound cuts out; sometimes only one sound plays. And after a few seconds of this, the game freezes. Here are some examples:
1. (ONIfreeze1_sm.mp4): In this example, two dupes are side-by-side working on paintings- one is making a blank canvas, the other is painting one. Only the painting sounds are playing. After a few seconds, the game freezes- note that the cursor still moves, but nothing else does.
2. (ONIfreeze2_sm.mp4): In this instance, at the start of a new cycle, the "wakeup" chimes continued to repeat until the game froze.
3. (ONIfreeze3_sm.mp4): Here, the dupes build a blank canvas and a compactor, but the building sound continues to play after both are finished- and does so until the freeze.
