That's bad. I'll ship a fix with the next update.
If you can elaborate a bit, like what stage you were on and what you were doing before trying to sleep, that'll make finding the bug a lot faster.
Thanks for the report.
Here's my save actually: https://pastebin.com/cF53W2NB
I am on Firefox browser (I have the dark reader, CanvasBlocker, and Ublock origin, extensions if those matter), as well as using Fedora Linux as my OS.
