Did you update Botania? Because you have Black/Dark Quartz Blocks missing.
Didn't know there was a new version out, guess I've just never bothered to check. I'll do that now.
Ah, okay, this explains it. I do have the latest version, but I set "darkQuartz.enabled = false" in Botania's config file since I have another mod (Thaumic Tinkerer) that adds its own dark quartz block, Smoky Quartz.
Is this intellij?
Yeah it is. I used to use Eclipse for Java stuff but at some point I switched over to IntelliJ; neither of them are perfect IDEs, but overall I've found IntelliJ to be an improvement.
