Ill try this here, since I haven't received any response on the windower forums or the github forums.
I was running windower 3.xx and was working fine even after the adoulin update. Then randomly one day it started crashing anytime Spellcast was forced to interact. I uninstalled, downloaded windower 4, used same plugins I have always used, and got the same response. If/When spellcast would do what it does, the game would crash. I tried uninstalling/reinstalling windower a couple more times, to no avail. I finally disabled spellcast, and voila, game works fine with all the other plugins that I use. I'm not the most computer savvy person, but can follow instructions well if someone has any ideas?
