53. Hang on, are you playing the original FTB Ultimate??54 haven't got far yet. Just have a turtle with a ruby pickaxe and a harvester. I have yet to find diamonds or make any real machinery.
It is however nice, though there are some features that I miss. Like being able to drag in a crafting grid or pressing ctrl to sprint. But other than that, its nice.
I also already found where my base is going to go:
I hope to be able to move everything to my new starter home, make a few machines and start another turtle excavation. Hopefully get enough diamonds for a chunkloader + diamond pickaxe. Yes, I started a server for solo play. Makes it easy to switch from desktop/laptop and makes gregtech a bit easier to deal with
