Hell, first time poster here (JUST got HL) and was trying to get this 3PP stuff (psionics and gestalt) going. Ran into several errors (mostly due to required packs I didn't have) but have now boiled things down to a point where I basically just "don't know what I don't know". Here is an image of my current error, involving Tome of Secrets.
