Defects pertaining to feats, proficiencies and leveling up.
1. The description for "Might of the Iron Legion" feat states that it grants 3 proficiencies; 2 for swords plus heavy armour. The heavy armour proficiency isn't added to the chrachter's list of proficiencies.
2. A non-thief character with the lowlife background has a +2 proficiency in thieves tools. If they take the "Lock breaker" feat at level 4, this proficiency is set to +0. I would expect that this should really be set to +4.
3. Sylvan archer feat suggests that it negates half and three quarters cover, but these cover warnings still appear in combat.
4. One feat in the list is labelled "Should Not be displayed". I'm guessing that this feat shouldn't be displayed.
