more spaghetti code
specifically it sounds like it's just the +2 all skills deal.
also I didn't want to add more confusion at the time, but i didn't do a save/load cycle when I verified this on one of my test characters. I did do a zone transition - I started on worldmap, rested with Hylea, entered an area, quaffed the luminous adra potion. Blammo, got +4 all skills. While there was an autosave and a zone load, there was no reloading of the game. Don't know if that affects any
