Where it goes
Is Supercritical required on the client, server, or both?
The project page does not say whether this file belongs on the client, dedicated server, or both.
The source does not explicitly classify this release as client-only or server-only.
What else does Supercritical − 0.2.4 need?
Supercritical − 0.2.4. Change the file and its required mods may change too.
Install MixinBooter, GregTech CE Unofficial, CodeChicken Lib 1.8.+ first, but 1 required mod has no matching file for this setup. Do not mix loader builds to force a match. 1 comes through another mod in the chain.
1 extra mod was pulled in by another dependency. Indented rows show who needs each one. We only count dependency files that match this setup. A file for another loader does not fill the gap.
