1.7.10 is actually quite well maintained by the GTNH team, they have RetroFuturaGradle but also seemingly a Nuclear Control fork.

Life is unfortunately too busy for me to try to work on this mod anymore, and setting up the dev environment for a version as ancient as this is also a nightmare. Honestly impressive that I got it to work two years ago. Unfortunate that my old computer for MC mod dev has had power issues and is too old to support modern software anyway.

Yeah they have quite a project, it makes me happy to see that it's still around and that they're still doing that. Too bad no capes :P that was my favorite NC2 feature

Got another report of this issue today, using the latest version (2.4.5a).
