Mathias,
Major Bug: The Spellslinger (Wizard) Archetype does not have the Exotic Weapon Proficiency (Firearms) feat bootstrapped as a bonus feat, and according to the book it is something the Archtype grants at level 1. This is a fatal flaw as it makes the archetype unplayable without it, the Spellslinger is a gun mage and needs that feat. I could not find a way to fix it but was able to find this bug for you.
