Anjimamia14 Do you in fact play on XBox? I ask because this is a relatively common issue on PC/Mac, but I don't think I've heard of it on consoles before. It has a master bug thread here:

The workaround should fix the issue for PC/Mac, and if you're on console, uninstalling Eco Lifestyle and saving with it not present should work equally well. Make a backup of your save before proceeding though, just in case you need it later.
