Just pulling this point out because I think it's kind of important and some people will miss it otherwise.I am glad for the day when Mystara receives the full 5e treatment. Yet, as another poster stated, there are some landmines which need to be cleared. That's what amends are for.
Anyone who wants Mystara to come back should probably be in favour of some kind of amends-based approach, because I can tell y'all, that the disclaimer ain't gonna be enough to save a 5E Mystara, if an unapologized-for GAZ10 hits Twitter, and from there, reddit, video game websites (which tend to cover TT RPGs now), and so on. It won't matter if 5E Mystara has been updated. Especially as then every Mystara product will be interrogated in some detail.
Also, just as an aside, I'm disappointed in some of my fellow posters in that they're so apparently alarmed by amends processes and focused on things like "Well it's not much money!". It's like, yeah, it isn't, but amends processes can be a really good thing and help people move on, and mean people coming to stuff in future react with "Oh, right, they addressed this properly!" not "Oh a generic disclaimer" then "OH HOLY HELL I WAS NOT READY FOR THIS AFTER THAT GENERIC DISCLAIMER!!!". They cause some short-term anxiety in favour of long-term gain. They're not a bad thing for companies to do, they just have to be handled right.
