[BH] [GF] Unable to mentor acting skill & instructors will not lecture

One of the things I was excited about from the Businesses and Hobbies marketing was being able to open an acting school:

• Get Famous Expansion Pack - Did someone say paparazzi? Open an acting school where you teach celebrities how to play the part!  

but there are several issues with trying to run or visit an acting school:

1. Acting has not been added as a skill able to be mentored. Sims can hold/attend acting classes, which require 3x mirrors and/or microphones to be placed nearby, but cannot be mentored when they're practicing acting on these objects.

[EDIT: Acting should be able to be mentored at the microphone and mirror like comedy/charisma skill can. It would be great if you could mentor while performing a scene too.]

2. Insufficient hobby class tasks: There aren't enough tasks available to complete a gold class when your active sim is hosting the class, let alone visiting from another household.

"Practice acting" or "perform scene" should be a task judging by what the participants autonomously do, but isn't for some reason.

I have objects placed with confident emotional aura in case "become confident" is a task that wouldn't show up if they're already confident. [EDIT: this is still the case after the 21 March patch. If sims are already confident, the "become confident" and "have 3 sims become confident" tasks do not show up and there are not enough tasks to get gold in the hobby class.]

This was a hosted class rather than an attended class.

3. [EDIT: Have not noticed this issue since 21 March patch 1.113.297.1220] When I started an acting class as a visitor to the small business, my active sim first autonomously used the microphone to sing and the mirror to debate instead of act. Debate/Sing were not assigned customer tasks.

Eventually she did practice acting, but would use the objects for the other skills too.

4. [EDIT: Appears fixed by 21 March patch 1.113.297.1220] The instructor would not take the lecture despite her only assigned tasks being hold classes and mentor skills. She was the owner and sole employee with L7 acting skill. Only my active sims would lecture in acting if I directed them to.

She was a celebrity, so I tried hiring non-celebrities and again visiting the lot from another household. They would not take the lecture. The visitors practiced acting, but the employees only acted if another sim autonomously interacted with "practice acting".

The guy playing video games in the lower right corner is also an employee. Both only had one task of giving lectures.

I've never used mods in this save and have repaired the game.

[EDIT: New issue post-patch
 5. Cannot buy entry at kiosk: this issue is only affecting this particular small business and is not related to loading into a household who is already at the small business, although this will trigger the same issue. I tried it with a few different sims who own small businesses. It triggers them to sell their own business and then buy a small business rather than buy entry.]
