I've had a colonist with 100% stress never go to the massage table that she was assigned. But I've also had this problem with a few colonists too. They've had full access to it, I've had them walk over to it, but they go and do something else often times it's to break something or vomit. It's frustrating because I don't want them doing that and smacking art decorations all over my base doesn't make a difference.
I've had my actions all set to priority 5 and the tables at 9 but nothing has worked and I probably just have to start over.
Steps to Reproduce
Set up a colony and wait until stress starts getting high before doing anything about it like building massage tables.
