Running into inconsistencies in my simulator

StevenBlea : I looked at both the full and stripped-down versions of your project. With all the variables and branching, I can't be sure if something in preview is supposed to happen or not. And, frankly, I'm not willing to spend any more time trying to figure it out. 

I suggest you follow the advice from previous replies: 

• Double check that the triggers refer to the appropriate variables. To help with this, check the variable count and usage. 
• Add variable references to the slides, and then preview it. That will let you see if the variables are changing when and how you want them to. 

I'll add a few more things to check: 

• If you have triggers that run "when [variable] changes," be sure you only use such triggers on the same slide that the variable changes. (The program doesn't "see" a variable change that happens on another slide.)
• Be aware that if a trigger adjusts a variable to the same value it already is (e.g., adjust a T/F variable that's already True to True), the program doesn't count that as the variable changing. A "when [variable] changes" trigger won't run in that situation.
• Check trigger order to ensure that the trigger that jumps to another slide always comes after any other trigger that happens at the same time.
