Hi! Omg I've been having this exact same problem for months now too!
I have tried EVERYTHING there is.
Not only have I tried resetting the mods folder etc,
I've moved the entire sims folder to the desktop to force another one to regenerate in it's place.
Which means I started from scratch. NO saves (which means it can't be a corrupt save file)
NO cc or mods at ALL. A fresh, newborn folder. So just the original files of the game and that is IT.
I make sure my game is repaired, up to date and also make sure the mod is up to date.
This is happening with ALL SCRIPT MODS so it isn't a problem that the modder can help with unfortunately.
I have ALSO made sure all language is in english...
The game works fine until the moment I put a script mod in. It shows in the CC/MODS window so it's definitely installed correctly.
As soon as I proceed and press play, it asks me to pick a season as if I'm starting a new save when I'm not..
Once I choose a season, it brings me to "choose a world" says I have $0 funds and basically won't let me play at all.
The moment I remove the mod, it's back to normal and my family's there again.
I have not been able to play modded since Seasons/The season update (and yes, everything is enabled etc)
At this point, I need serious help, and I'm a minute away from literally HIRING AND PAYING A PROFESSIONAL TO GO THROUGH AND FIX IT.
I've been trying at this for months and months, googling, researching. Nothing. Nothing has helped at ALL.
