So, I tried to apply this to my modpack, it works, but there appears to be a pretty spectacular bug...
I'd like to use this in my modpack, but some reason why this is happening and a fix for it would definitely be useful first.
To be specific, my whole world loads great, but looks like this. I can move around fine, I can interact with all blocks and entities fine, but not a single block ever loads. Even exiting the world and reentering, as well as changing graphics settings.
This was also definitely the only new mod I added, so although I have no crash report, fastcraft is certainly part of the problem. Unfortunately, another mod has given me enough logspam that I can't find anything about this in there either.
Also, on another topic, it'd be nice to get this compatible with the betweenlands mod. Last I checked, they had given up on figuring out what was not working between the two.
