I have Tournament off of my familiar cards list. I pressed the bot game button for "1 Bot" and played a game, I rematched that bot and Tournament was one of the cards.
The settings for the table were that familiar cards should be respected, and I double-checked that tournament was not one of my familiar cards.
I've experienced the same issue upon rematching with a bot.
ok I found a bug & fixed it. It wasn't specifically related to the rematching, but it still seems to have been the cause here.
If you had max_unfamiliar_cards set to 0, the first card selected could still be any card you owned instead of just cards you were familiar with.
