In the past, the process of drafting has produced text in output_log.txt that draft assistants and trackers use to provide users information about current and past drafts. The draft assistant I'm working on was not providing me any information during any of the Ikoria Traditional Drafts I played yesterday, and examining the log file during the draft revealed that it was because none of the normal output was being produced, even in a modified form.

I'm not sure whether this is an isolated bug or something that's an issue globally. Given that I haven't seen any chatter about draft assistants breaking, I suspect it's isolated, but I'm not sure (the set is still 1 day old).
