Hi Max, thanks for testing and the great reports :) I've uploaded the zip file again, please check if it works now :)
I was able to unpack as usual.
I tested now the new version a bit. I like the new ore textures! and performance increase.
One Suggestion I have, is it possible to make the Particle of breaking ores, different for each Ore?
Like nugget like color for the Gold Ore, Gray for Iron, and so on? I notice that the Dirt has dirt Particles, but the Ore were all the same with black/gray.
I guess this would give the Visual Look an Improvement. Additional to some Stuff, nano_dodo had listed.
