[BH] [SD] Massage from employee in a small business cancels immediately

I don't think this has to do with Businesses and Hobbies specifically because this same issue happens with a played sim tending a massage table. The sim being given a massage will cancel the massage to request another massage and this will happen repeatedly so no massage is ever completed. This happens both with massages that are requested by an NPC and massages that are offered by a played sim.

I am experiencing this issue as well. Massages are not completing and the sim getting the massage gets up... or the masseuse gets the naked sim alert from the client and doesn't complete the job. 

I have the same problem, along with many others. "It's been months and still hasn't been fixed"

I did karaoke and they barely sing.

and I'm tired of the weather inside the houses.

Having this exact issue as well. 

This happens to me as well. I used a cheat to max out the Wellness skill for testing, and the same issue occurs—the massage gets mysteriously interrupted. The only way to complete the process is by offering the massage to Sims visiting the establishment.
