Was just about to give up and post a new topic about this after doing everything I could think of to fix the weird error I was getting that was preventing deployment before doing yet another Google dive on AddIns.xml and finding this thread. Agree that some kind of warning on the site would be nice to prevent others from expending so much time/energy trying to troubleshoot something that isn't currently fixable. Looking forward to using Vortex in the future, as looking at DAO Mod Manager now and it's already considerably more complicated than I was hoping. :pinch:
