@Stormkeep another update. I tried again and all the sims in the club seemed to prioritize using the onsen than doing the club activities. I got them to snowboard together and they lined up and did it which I was happy to see but two of the club members were kinda frozen at the bottom of the slope. And they were glitched into each other. Then because I made them snowboard one time instead of continuously, they went back to the onsen. I thought that maybe if they were close to the slopes they would do it autonomously. But nope they still prioritized the onsen.
So I'm not sure if it's because of the onsen lot. Maybe if I had them gather somewhere else... but idk where else it would make sense for them to gather. Since I want to set it up so they will be snowboarding and skiing if I have another sim outside the club visit the mountains. From my understanding if I set a rental lot as their club gathering then they will only gather when a sim is at that lot. And if I had a sim rent out the rental they gather at then they will always be there and go inside the house and etc.
I will try it again without mods and then try making a bug report.
