The cause of this issue is this piece of code that is executed after each episode

https://github.com/jerry871002/bayesian-strategy-inference/blob/6c9084ae8e3ab8e2f09122c4f1e824a907ffaf88/src/baseball_game/run.py#L323-L355

The problem was that if the intra-belief happens to be uniformly distributed (which is quite unlikely, so the error does not happen every time), the code enters the first if block, and the step_i_policy_preds arrays aren't properly "aligned", causing the next episode having an IndexError . (i increased but the length of the array wasn't)
