Where it goes
Is PsiTweaker required on the client, server, or both?
Installation on the client is optional. Installation on the dedicated server is optional.
The source marks this as usable on both the client and server.
What else does PsiTweaker 1.20-1.0.1 need?
1.20-1.0.1 on 1.20.3 Forge. Every mod below is checked against that same setup.
Install Psi first, but 1 required mod has no matching file for this setup. Do not mix loader builds to force a match.
We only count dependency files that match this setup. A file for another loader does not fill the gap.
