New episode not updated on bot

I published an episode for my bot but changes I made to that episode later wouldn't update in the bot no matter how many times I saved/published them. In an attempt to get around that problem I then unpublished that episode and publish a new episode. Now, the bot doesn't work at all. I click publish but that new episode is still marked as unpublished and the bot has the label of "Pending Channel Update". Am I missing something? Any ideas on how to proceed? Thank you.
