Feats are now loaded correctly from the PDF. Yay! On top of that, custom shields like "Light Shield" or "Dragonslayer Greatshield" are now also exported using some custom item generation logic.
The next big feature I'll be working on is to allow merging of a MPMB sheet with an existing FoundryVTT actor/character. This will allow you to level up a character with the PDF, while being able to keep the money and items the character gathered while adventuring in FoundryVTT. More on that later.

Keep being awesome and may the dice be ever in your favor.
