None of those really pertained to my issue. The files in question would go into infinite load when trying to load various lots. Played or unplayed Sims on it, vacant, Maxis made original lot, made by myself, downloaded from the gallery. None of them would load. So it would load into the current family just fine, but if you clicked travel and tried to leave the lot, it would infinite load. If you tried to go to the world map and then pick a new location, some loaded just fine, some infinite load.
The odd thing however, was turning off Mods sometimes worked, with them fully disabled I was able to load into anything. Turning mods back on and running with 50% of the mods folder, if I recall all tests failed, it even failed with no mods in the folder. But then a later test, it worked with like 99% of the mods folder, I had removed 3 mods I suspected was the cause. But then it failed every test with or without those mods in the folder at all, including the same test that previously worked with 99%.
My only conclusion is the file is corrupt somehow, a save 1 month prior to the ones being tested works 100% fine and has continued to work the last 2 days, so I simply reverted back to that one and just lost a bit of play.
Infinite loading has so many causes. Wished the game would give more indication what's wrong.
Glad your backup works though. Make sure to keep regular backup in case things go south again.
The back up failed a few days later. I ended up starting over. Spent 2 days, 16 hours total saving all the families and lots I wanted in all 26 worlds and loading them into a brand new save. My save file is much much smaller and game loads a bit quicker now and so far hasn't had any issues at all.
