Problem Description

Issue

After adding mods to try and play a Modpack (“R.A.D 2”) with our friend group the server hadn’t changed the version yet so I stopped it in order to do so. But now it wont start up and is giving us an error message in the console.

Reproduction Steps

• Added mods
• stopped the server
• cannot start

What’s the error message?

I know a fair amount about Minecraft modding and I have had the same problem with my server where it would not start after adding mods. One thing you need to do is to make sure you have the API and Lib/Library mods installed. Those types of mods basically allow other mods to run correctly.
