Hi, I started playing on 1.7.10 with a custom modpack a few days ago. It's going smoothly except one very annoying bug: some chunks will just randomly turn black like they don't exist. The only way to fix it is leaving the area of the chunk or reloading the world. (F3 +A does nothing) It's not caused by Fastcraft as I tried it without fastcraft already. Anyone know a quick fix to this?
