Vanilla With Some Sugar

My goals with this pack are to keep it relatively light and to not stray too far from vanilla. The only tech mod I added is Refined Storage because I hate having hundreds of chests :D. There's only a few "big" content mods such as Biomes O' Plenty, Pam's HarvestCraft, and Tinker's Construct.

In my testing it seems to be fine with 3 GB of RAM allocated, but try bumping it to 4 if you run into issues.

• Biomes O' Plenty | Lots of beautiful new biomes to explore. Compatible with ZAWA.
