So, I've been playing with this content a bit more, and decided to do some troubleshooting to see if I could get it to work or any more information about why group meditation classes fail. I've tried different lot types, household sims versus NPCs, etc. It does look like the bug is related at least somewhat to lot type.
- Group meditation classes fail about 90-95% of the time on residential lots. It fails with both household and NPCs sims as class members. The instructor and the class members both cancel out of the interaction on the transition from waiting for the class to start to the class actually starting.
- On select public lots, including spa lots and libraries, the instructor does not cancel the interaction during the transition from waiting to in class, but does cancel occasionally. Some class members do cancel out, but generally not all of them. It seems like household members are more likely to cancel out than NPCs. This is more likely to succeed than holding a class on a residential lot, but this is still error-prone enough to be frustrating.
- It seems like cancellation happens more frequently when there's another action lined up in the action queue, but this is also not 100%.
