1. Circumstances
Using Macbook Pro (Catalina 10.15.2), and with Royalty installed. Version 1.1.2647.
2. What happened
Around 20 minutes into gameplay, Rimworld locks up. Gameplay sounds continue and loop (around the last ~3 seconds of audio, looping). All input it locked, and touchbar controls become nonresponsive. Hard-resetting the laptop produces a glitched white screen for a second before restarting.
3. What's expected to happen
For this to not happen :)
4. Repro steps
Can consistently reproduce just by playing Rimworld for around 20 minutes per session.
Could you please upload the logfile? Maybe it's related to FMOD errors flood.
