So I have a few bits of news.
I will submit V2.1.0 in the next day or so, and it will contain GalactiCraft. Doesn't have the custom multiblocks since I came up with a pretty cool plan for it that won't need that much work. The only bad part about V2.1.0 is that I have dropped Realistic World Generation due to certain things (Jungles, Swamps) not generating. This is all my fault for including a early alpha mod in a modpack designed for long term worlds. So you may or may not need to reset your world, I don't know what will happen, RWG adds no blocks so it might just make a weird boundary. I have replaced it with the Highlands mod, it offers many of the same benefits such as epic mountains and is more complete.
I have also changed the minimap to OPIS, I feel like it is better for GregTech as it allows you to look at your world map. This makes it easier to plot out mineshafts every 3 x 3 chunks.
Another bit of good news, The newest version of Bluepower changed volcanoes to be the most epic world generation I have ever seen. (They're glorious!)
I flew around the world I was in to make recipes and found this:
And they get even bigger... I don't have the picture, but I found an absolutely massive one in another world.
*Raises glass to Bluepower devs.
EDIT: I am going to delay the update until after GT6 comes out. GT6 WILL need a reset unfortunately, this way you won't need to reset after this update for the foreseeable future. (A Long Time)
EDIT2: I probably will just release it once V4 of Reikas mods drop, GT6 getting to the state GT5 is in atm MAY take longer than I thought, also I have decided to go with no special biome/world generator. Vanilla is perfectly fine and honestly I find that a ton of fancy biomes can actually get in the way when you want to find a specific one.
