I added four cards to the errata list today: King Saul (CoW), Joab (CoW), The Roman Jailer (TEC) and King Abijam. With the change to the warrior/weapon symbol layout, these characters only had the warrior symbol on one side meaning that in today's rules they would only be warriors when used as that side. When we made the decision to go forward with the layout change, we decided that these characters would remain Warrior-class on both sides (as Heroes and Evil Characters). It is our goal that future printings of these characters will be updated to reflect current standards.
I'm fairly certain most people have continued to play them that way, but wanted to be certain it was codified.
I also added a list of cards (so far just 2) that formerly had erratas, but were removed in the last major update to the errata list prior to FoM. These cards were found to have been errata-ed to an "intended ability" which we have moved away from in recent years.
