[BH] Some lectures and classes don't work.

This topic is a bug report, and not a feedback. The cause is clearly identified and I'm providing all the information needed. If there was a reason to move this topic to the feedback section, I would love to understand why, and have an explanation please.

List of affected Classes:

• Fabrication

List of affected Lectures:

• Fabrication
• Robotics
• Research and Debate

I tried to start a Fabrication class using the whiteboard, and I noticed that my customers were not using the objects around, and I was only able to teach Rocket Science at the whiteboard after launching it.

It's a pretty easy to see the issue when I look at the tuning: the interaction to start the class launches a Rocket Science class situation instead for the instructor. 

There is also an other issue while trying to hold a Fabrication Lecture, that I tested with no other mod installed other than the Better Exception: the interaction that is used to make sims join the class causes an issue (the issue is thrown every time a Sim joins the class).

I don't have this issue with other classes, so I don't know what is different here. Tested on multiple lots.

I found the cause: contrary to other hobbies classes broadcasters, the one from the fabrication class uses the "simPicker_HobbyClass_Whiteboard_LectureFor_Fabrication"  interaction instead of the "sI_HobbyClass_ListenToLecture_Fabrication" interaction. 

This issue stems from 1 line in 4 tunings, and would be very easy to solve :
