Re: TS3 Seasons (stuck in winter + stats not changing)

@VinylCorder  I'm going to start with the last question first:  Yes, deleting any sim can and will corrupt your save.  A testingcheats object-delete only removes the sim's body; other data stays in the game and will continue causing problems.  If it's possible, it would be a good idea to revert to a save from before you deleted the parents.  (In the future, you can tell them to move and select "kick out," and they'll find a place to live on their own.)

Your male sim sounds corrupted as well.  Resetsim doesn't do much except unstick a sim that can't move; it's not going to fix this issue.  Your next step, without mods at least, would be to evict your sims in Edit Town, save their house to the bin, bulldoze the lot and replace it with the bin copy, and move the sims back in.  If you do this all in one Edit Town session, the sims will keep their jobs and relationships but lose their promised wishes and opportunities.

Failing that, or if the world shows other signs of corruption, you might want to save your sims to the bin and place them in a brand-new world.  They won't know anyone, but they should still have their skills and their relationship with each other.  Hopefully, your male sim isn't too corrupted for this to help.

By the way, before you start trying to fix these issues, it would be a good idea to use "save as" to rename the save, thereby generating a backup copy of this save.  That way, you can always revert to the backup if you don't like how the troubleshooting went.

And yes, it can still snow in early spring.  The weather is random to some degree, but the transition from winter isn't supposed to be instantaneous.  If spring keeps looking exactly like winter, though, that would be a sign that the save might be corrupted.

The clean folder was a good idea, and I'd have recommended starting there if you hadn't done it already.  But unfortunately, that's not going to fix corruption within your save.

P.S.  There is no "Seasons" section, this is it for all TS3/Windows-related issues.  (There's a dedicated mac section for sims games as well, but that's more about technical issues than gameplay.)
