• Possibly fixed issue with mana regen stopping randomly
• Changed spell loading method
• Various improvements and bug fixes

I haven't had a lot of time to do some thorough testing. I believe everything should work, but I make no guarantees. This is why I'm releasing this as a "beta" version instead of a full release version. If everything goes well I'll just change it to a release version.
