It could be tied to Steam?
I tried latest package this morning. I tried only installing the one side panel mod (and restarting twice). Still no luck.
I know troubleshooting something you can't reproduce is impossible, so if you need me to send logs or if there is a debug mode I could enable some logging on that I could forward to Autospy or yourself to help you just let me know.
And, Thank you for looking into this!
