When playing in a long-term save you will notice the calls to ask to stay over never happen. However in a fresh save you will receive calls, until a point happens where no stay-over calls happen ...
Ideas
I installed Kuttoe's bug fix mod like two weeks ago, and I'm still not over how many calls I'm getting? I spend thousands of hours playing this game, and all the invite calls I ever got was hanging out at friends house/friend hanging out at mine and the club party at nightclubs or the bluffs calls from Get Together. Now I'm getting invited to festivals! I'm getting invited to bar nights! I had two stayover calls happening! Did you know that apparently Businesses and Hobbies has a mentorship meeting event, where if your sim has a sim mentoring them, they can be invited out to community lots somewhat relating to the mentored skill?
(Also various mods I have tried over time to get more/different invite calls suddenly work now. I really like having my sims invited to things, but the game rarely did that, and all the mods I tried also didn't seem to work for me, so I always tried them for a bit and then uninstalled them again, disappointed they don't work. Turns out they do work just fine, as long as the event schedule cooldown is fixed first.)
Please fix the bug in game, it really limits the playing experience, and players miss out on various features the game has.
