Hi! First of all thanks for your hard work on this project and thanks for updating it to 1.21.4. I've been looking forward to play this mod for months!
now this happened. I installed the mod and creative core. Was playing in the nether dimension, I was caught on lava, while i was dying the animations played smoothly and then I burned to death. After clicking on "respawn" the game went to "loading terrain" since my spawn was on the overworld and crashed on the loading screen. Then I clicked on "play on the launcher" (official one), fabric loader. and from this point onward everytime I opened the game it would display a dark screen instead of the menu, the menu music plays and I can click in the game menu but I can't see a thing

When i removed the mod from the mods folder I as able to enter the game and see the game menu again, then i joined my world and I believe a creeper exploded in theoverworld where i respawned while it crashed and it caused the nether portal to display buggy.

Thanks for all ur hard work! the mod is

amazing!

I have the same issue, but just from the first loading it doesn't seem to render the main menu, as I can still click the buttons and hear the sounds. This is the log I get

latest.log

Should be fixed in the newest version. Sorry for the trouble.
