Just uploaded 1.9. Minor bugfix release; a few unusual papyrus issues solved with TES5Edit where script properties weren't displaying in the CK. Also some more performance tweaking in the Luminatory. More fixes listed in the readme file.
I was going to make an .esm but it seems the CK has a few problems making a valid file from the Wyrmstooth.esp. I probably should've started with an esm to begin with but hey, you live and you learn. The idea of Wyrmstone and Brimestone gear has been axed; I think Wyrmstooth 1.9 scraqed into Steam with only 1mb to spare this time so I can't fit in any more custom content.
There may be a 1.10 if any really serious issues are discovered. Other than that, I need a break.
