Here's a patch to fix brevven's and K2's mod support https://gist.github.com/Acxd25/71d506e665aa84859dad258e41734b8e

🚀 Version 4.0.1 of Extended Vanilla: Refining is LIVE! 🚀

Fixed some things here and there, in order to:
⚙️ Mod compatibility restoration: Bz mods and K2/K2 spaced out are now playable again in combo with Ev Refining.
🚆 Also, I noticed that the Rail crafting could get improved with gravel, so now you're able to alternative-craft them.
