JATiCA
Add JAOPCA materials to Tinker's Construct
Quick answer
Which JATiCA release should I use?
jatica-1.1.0.jar targets 1.20.1 with Forge. The project page does not say whether this file belongs on the client, dedicated server, or both. All 3 required mods have matching files.
Where it goes
Is JATiCA 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 jatica-1.1.0.jar need?
jatica-1.1.0.jar. Change the file and its required mods may change too.
Install Tinkers Construct, JAOPCA, Mantle first. We found matching files for this game-version and loader setup. 22 come through another mod in the chain.
22 extra mods were pulled in by other dependencies. 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.
