Re: Sim can’t use Invention Constructor

She’s had 4 eureka moments. Everyday it asks her to brainstorm and invent on the invention constructor but she just waves her arms around with the crossed out footprints bubble

I'm adding this answer here because I was confused when my SIM couldn't use it and I couldn't find an answer.  Then I realized there was already an invention laying on the floor of it.  Once he moved that out of the way, he could interract with the inventor.  No idea why a ray gun was already on the platform but that did the trick.  Now he can use it every day like normal.  Hope this helps anyone else whose experienced this.
