The problem currently is Rubidium, sadly. There's a glitch currently where it cannot render lava blocks interacting with clear blocks such as grass. The next update already has it fixed, we now just have to wait for it to release.

Any idea when this update might happen? kind of unusable as it soft-locks a world after a bit

rubidium-0.7.1a.zip

Here's a unofficial fix made on the discord for the mod. There are still a few issues like Oculus being unusable and other minor things but the game should be playable.

That fix worked for me! Thanks!
