I will have to look into this. I have slept though the night repeatedly to progress time to test other things in April and may and didn’t have a problem. But that was one day months and sleeping as soon as I woke up.
I can also help you do some bug testing if needed. I did a few more tests this morning. One where I removed all mods and just sped up time and eventually same thing happened but on a different month. Animations still happen but the time freezes then eventually I can’t even pause the game and it won’t take any commands from the mouse or keyboard.
What I did notice is in the environment file in this save the current day and monotonic day did not match (no idea what that means) but what I noticed is if I alter those values it will let me get past the freeze. However the freeze would happen again a few months later.
I can definitely do that. If you don't mind messaging me through discord I can get back to you faster. My name on there is Nyzzio it might not be capitalized though. Where is the log file stored?
I'm also running a test on it right now with my laptop to see if it is isolated to just my main desktop or not.
