Hi @Sharlikran and @Baertram,
I want to seriously thank both of you for your continued input and for taking the time to respond to my posts. While I don't (yet) know how to code, I have an engineering background and am very inquisitive by nature. I am doing my best to try and learn and hope that in the future, archived posts like this can provide valuable information to people like me!
Whether it was addons not playing well with each other or something else, prior to being updated late last night Inventory Insight was (at least in terms of disabling it resolved my issues) the offending addon. LibAsync was never the issue (except maybe that it removed LibStub support which IIFa depended on?).
I also want to further clairify that while I still use Minion to manually update my addons when available, I started using an alrernative method to re-download all of my addons manually each time something broke/stopped working/bugged out/etc...
My method was to completely delete my "\Elder Scrolls Online\live\AddOns\" folder and then use a 3rd party download client to manually re-download the latest copy of all my addons (note that I don't use all of them at the same time). I would then extract everything and paste it back into my "\Elder Scrolls Online\live\AddOns\" folder. I would also prune (or sometimes completely delete just to see what happened) my "\Elder Scrolls Online\live\SavedVariables\" folder. Doing so either didn't help, or helped for a small while and then issues would start up again shortly after (without any additional changes to the game or my addons). That leads me to believe that something could be self corrupting itself?
