And you know the other thing about Han and Greedo? It's a change made in a way that you can't go out anywhere that I'm aware of and watch the original version without spending whatever to buy a used copy of the original VHS movies on the 2nd hand market. I don't have Disney+, but I'm going to go out on a limb and guess Greedo shoots first in the version they have available on that platform just like he did in the DVD version I bought however long ago that was.See my comment above.
But I'll give you Han and Greedo. Nobody's perfect.
If you like the original Ravenloft lore, WotC supports that by making the old books freely available on DMs Guild. You absolutely don't have to use anything printed in a WotC 5e book, you're absolutely free to use the old lore or better yet, make up something that's tailored to YOUR players. I spent a ridiculous amount of time playing 2e Dragonlance and my group never once encountered Tanis or any of the other heroes because I changed the lore to have them not exist. They later released the 5th Age material and my group noped out of that one and kept playing in the setting we knew and loved the way we knew and loved it. It wasn't exactly complicated either. I realize from history that won't stop you from replying with a complaint because reasons but this fixation with lore being changed is pretty silly to me. How many versions of the Arthurian legends exist? Stories change, people move on. Well most people do anyway.
