That's not really a lot of information for me to go off of XD But someone else reported a similar thing and I'm in contact with the company responsible. If they don't fix it, I have an idea that should work instead! But I'm not sure if it's the same issue you're running into.

Hey! Steam isn't the solution. But if Ruffle.rs ends up working out, at least I could keep my oldest games online! Almost anything made after Mine Blocks will be ported to Haxe though, so I wouldn't worry about those ^^

Use any three dyes other than bone meal and lapis, and you'll be all set (but the recipe should probably accept those too, you're right!)
