IFPatcher
Patch some known bugs from Industrial Foregoing for 1.12.2 as it is officially EOL.
Quick answer
Which IFPatcher release should I use?
IFPatcher 2.5.0 targets 1.12.2 with Forge. Do not install it on the client. It must be installed on the dedicated server. 1 required mod needs a matching file.
Where it goes
Is IFPatcher required on the client, server, or both?
Do not install it on the client. It must be installed on the dedicated server.
This file is marked server-only.
What else does IFPatcher 2.5.0 need?
2.5.0. Change the file and its required mods may change too.
Install Industrial Foregoing 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.
Before you install it
Add IFPatcher without breaking your instance.
