I'm experiencing the same thing except I'm having a problem with Mr.Burns and Smithers 60 minute task for Smithers to exercise for Mr.Burns at first I thought it was because I was whacking snakes because it had seemed like that was the only thing making them stop until I wasn't whacking any snakes so they could finish the task then that's when I started realizing it couldn't just be because of snakes.... Does anyone know how to fix this or what's causing it??

It's just a glitch, it's happened with some tasks before. They'll patch it eventually with one of the next updates.
