Yeah I saw this. It's crashing because the number of people in the affection list is no longer evenly divisible by 8.
Easiest way to fix:
Delete 
game/notification.rpyc (it will rebuild automatically)
Then edit 
game/notification.rpy in any text editor. On line 2, add "import math" after "init python" like this:
	
	
	
		Python:
	
	
			init python:
    import math
    #positiveColor add the "good" color to increased stats (green)
    # rest of file goes on as before
	 
 Now find the function named "screen affection_screen():" ... we're going to change the way the "number_col" variable is built with the math library's ceiling function. From this:
	
	
	
		Python:
	
	
			        $number_col = len(discoveries["Characters"])/length_col
	 
 to this:
	
	
	
		Python:
	
	
			        $number_col = math.ceil(len(discoveries["Characters"])/length_col)
	 
 Adding 
math.ceil( before the call to the length function, and 
) after. Don't forget that closing parenthesis.
Save the file and run the game. It will automatically rebuild the rpyc compiled version of the file, and the affection menu will now work.
