Crin,
In regards to "EA's stuck sim check" and how it operates:
I have had a BP save that is about 88 weeks old now, and I was having so much trouble with it freezing/lagging all the time I just stopped playing. - why this matters? I tried reloading it after having to do a clean reinstall due to an Origin error downloading FLS via DD. So, in doing so my BP save only took 15 minutes to load (vs the usual 40minutes) and with that being said prior to patching to 1.55 it got laggy really quick into gaming. Within the same "sim day" I was choppy and lagged out. Went away quickly after resetSim * , but came back again. Then I read your post about this new EA stuck sim check and I went ahead and patched confident the game was in good order again. I patched with no problems and tried my BP save again.
I can say that I played the same amount of time as last night and I never got that crawling lag. At some points it would lag for a second or two (sims time jumping a couple minutes) but then the game would go back to smooth play.
I want to argue that the new EA Stuck Sim check feature operates AS THE STUCK SIM ERROR occurs. I say this because of the difference in gameplay in my BP save ( I never saved either "test play", just exited)
Somewhere in BP I have a critical routing error. Based on Written_Reg's posts Ive read over the past couple years I would imagine its due to my placement of additional lots and changing a few of them around. (moving the school, adding the Binder Clips center, etc).
So just wanted to report what I found and why I think their new feature does it as the error occurs. After I patched to 1.55 I didn't get any lag and prior to patching I had lag.
I'm offering this here because I believe it's where I saw you say we'll find out how it works when simmers who don't have Twallans mods installed can verify.
Hope this helps :) Personally, I'm excited because it looks like BP is playable again! The lag would be so bad you'd get frustrated just waiting for 3am to come around so you could resetSim* all. ( I gotta find where the problem is)
