Assertion with DiscreteValueIteration when trying to solve MDP

[seth.e....@gmail.com]

I've been trying to use POMPDPs.jl for our project. We have a fairly straightforward MDP problem and I was using the GridWorld notebook as a reference for making our own MDP object. I've been getting a strange error when trying to run DiscreteValueIteration

Any idea on what this issue is? I can send you the notebook if you want to look at the transition,reward,... functions of the PitchCalling object

(For other readers: After discussing this in person, we found that some of the transition probability distributions had all zero entries)
