That's a great news! Though cross-referencing the compendium v0.8.0 (6 July 2018), I count 6 errata so far that have never been printed (except for Promos):
- 108 Worldly Desires - (Dirty Deeds #1)
- Hot Lead Flyin' - (Core Set #121)
- Morgan Cattle Co. - (Core Set #3)
- Nicodemus Whateley - (Faith and Fear #19)
- Rico Rodegain - (Dirty Deeds #13)
- Smiling Tom - (Election Day Slaughter #2)
108 Worldly Desires being banned and Rico/Nicodemus being only available at the event, there are 3 cards left; and I'm sure there will be more as the compendium having been developed over the next months.
For those who are not able to attend the organized plays, please make them available, at least, in the PEG online shop.
