I want Clark Kent to be able to use any one of 3 phone booths to change then I want to inactivate the other 2. Any ideas on how to do this?
Hmm....good question. I don't think there's really a way to do that. You've got a 'starts when' option, but not an ends when. I'd say the best you could do is either just add multiple phonebooths, but only have one linked to an encounter OR have multiple phone booth encounters, and just hope your player doesn't click on the others.
I was afraid of that. I'll just break this up using sub-missions.
Sorry I couldn't offer more help, YL.
