From the new season guide "If an ability-score-dependent feature of a class, prestige class, or archetype is altered at any time, you canrebuild your character to its current XP"
The most generous interpretation of that would allow a complete rebuild of Lore-Warden's since the bonus feat that was granted allowed you to by-pass ability score requirements. If you had 13 INT though your the feature does not really rely on an ability score.
John Compton's already addressed that. He's said he doesn't agree with that interpretation but that Lore Wardens could be up for a special dispensation rebuild prior to the adventurer's guide stuff making it into the PRD.
You can see that here.
