I have had this happen twice, the last in this game: 176154899
One of the bots plays a card and it freezes like it doesn't know what to do.
In this case it played a Forager, trashed a card, and froze.

Thanks for the report. It's known that bots often (but not always) have trouble dealing with debt. Your game seems to be one of those cases.
Solving bot problems may be one of the areas being worked on after the release of the next expansion.
