Can I get a link to 1.01 changelog?
Check the support forum for changelogs, and check the change log often. They're a living changelog up til release of the patch as more things get fixed and added. This one has probably doubled in size just today.
Also, to clarify, after the 1.01 patch, I will not need "Enchanters" , only "The Decalon" to be able to purchase and use the elemental magic books? Correct?
EDIT: I'm also certain that it's a fairly simple .XML fix to correctly hook this back up, but I don't have the game files in front of me, so I can't say exactly what it is. It should be easy enough for anyone to bandaid this themselves if someone can sift through the XML and find the part that's broken.
