Are they sure it wasn't the cranberry sauce's fault?

It's really down to DM discretion. The 2024 Dungeon Master's Guide does give some lip service about degrees of success, but it's completely optional. The 2014 core rulebooks don't mention it all, I believe.

I'd watch it.

Handsome set. Looking forward to a review if you do one.

Congratulations! It sounded like your group had a lot of fun and I'm sure they will in your next game as well

Amazing year. Congrats, Seth.
