invoking self.running = False doesn't stop simulation

[Joe Hancuch]

Hi - I am attempting to kill the simulation right before my agent reaches the end of the grid which is 100 x 200. 

I have self.running = True and when the position of my agent equals to the y coordinate of 195, an if statement changes it to self.running = False. However, my simulation keeps on running and I get the below error message when my agent steps off the board. 

I am not sure why my simulation is not stopping when self.running = False is invoked. I have also included the three files for reproducibility with the important lines highlighted.

It is difficult to review the files because they are rtf and not .py files. 

My guess is something is happening in the execution of the count_type() function. You are passing "Done" as the model? 
It seems to be failing silently. I would add a bunch of print statements to step through where it might be failing.
