The issue is resolved, both are working.
But to understand why it happened, I might need to be more detailed, in case someone else has the problem, to look for solutions.
As mentioned, the problem occurred after latest Windows update. Everything looked ok (no errors displayed). But I noticed my wallpaper suddenly missing. I thought nothing of it, until I noticed my The Sims 3 to be gone gone. It just went poof. But I ignored that as well, even though I considered it a high risk anomaly. It shouldn't have happened.
Now, I went for the usual by-the-book procedure. Chkdsk, Sfc and DISM. All ok.
Still the games wouldn't work.
Then went for restoration of default Windows services. Still same problem. Then went for default registry permissions. Still problem. After that restored default ntfs permissions for all files. Still same problem. Then did group policy restoration. Still same problem.
After a while, I saw an article about latest Windows update bricking computers, deleting files, removing wallpaper and causing BSOD. Assuming that happened to me, I went with nuclear option (reset this PC and remove all files). The only change I had before nuking was to turn off Windows defender/security.
So, from inside Windows I nuke it, I boot into fresh Windows 10, update it no problem but I noticed that Windows defender/security was still disabled. Assuming Windows 10 image to be corrupted even though DISM reported everything to be ok, I had Windows 10 on my USB and nuked it one more time.
Using PatchMyPc I reinstalled most of my programs, so after I installed Steam I started downloading cca 600GB worth of games.
When finished both CMANO and CMO with all dlc and workshop, I tested bothand now everything is ok. Praying Mantis with CMANO and No time for Mischief 1995 for CMO.
Question 1: Where to find Game Speed button in CMO game panel? (I know about game option in Game>Game Options)?
Question 2: Any possibility to bring CMANO speed optimizations in CMO (pulsed mode etc? Sim is heavy on "it belongs in a museum" hardware)?
3: I work on cruise ships for 7+months per contract. Can we have All database images/descriptions downloadable as part of workshop with all maps divided by Continental theatre (North America, South America, Europe, Asia, Australia, Africa) and by oceans? I sometimes love to play on new maps even though 1 second simulations may take me 15 seconds real world time (until I upgrade)....
Good detective work!!
