No worries I can completely understand I was gone for over a year due to personal issues. I came back a couple months ago after being gone since Dec 2018, so all my A17 mods were useless with all the changes since then till now, took me a couple months to get everything working, recompiling over 259+ unity packages to update those and all the modlets I made as well. Lots of trial and errors.
I heard the same thing on the UMA which I was really upset about since I created over 140+ ones for A17, but from what I see a few things changed on them but still working so far. Not sure when they will actually pull the plug on that but it is still there for now.
