Nakazo

Actually I just solved it, the issue was with the wrong version of Forge

Hi, so I have put together a custom 1.7.10 modpack here: https://www.technicpack.net/modpack/nakazo-modpack.1076669 The issue is that on play instead of opening for me it is crashing and bringing itself back to the technic launcher right away. Below is the log for the crash inside technic launcher: [B#349] 2017/08/09 17:30:17 [WARNING] File version.json not found in

Any advice? Edit: I should mention that I have run Hexxit before, and that works fine
