Heya. When they do changes to a 2DA file, or a group of 2DA files, they do a complete restructuring in order for them to mesh and that is why they get tagged as being changed even if they haven't. If any Obsidian Dev wish to correct me please do, but its just part of the QA process to double check everything that one 2DA change won't effect another 2DA file, which is always good to have them double checked. Besides the patch works, the game is now better, and I for one am eagerly awaiting 1.06 and the expansion!

LONG LIVE OBSIDIAN!
