Mage armor is still bugged to the extreme.

It gave me +5 AC on my Watch armor for a whooping high AC in leathers.

This seems to be a problem solely with armors with non-universal armor bonuses, which is less than ideal considering how few armors with universal armor bonuses we have. I have absolutely no idea what's causing this, but if I can't find a solution soon I'll revert to the old system (which allows for Mage Armor to give negative AC).

This should be completely fixed.

For sake of reference, Mage Armor should give up to a total armor AC bonus of 4 minus base AC of the targeted armor, down to a minimum armor AC bonus of 0. Mage Armor does not stack with, or figure in, already existing temporary or permanent armor AC bonus effects present on the targeted armor. The spell must still be targeted on a creature.
