Minecolonies version

Multiple versions tried:
Version: 1.12.2-0.9.141-ALPHA
Version: 1.12.2-0.9.4-RELEASE

Expected behavior

• Game loads without issue.

Actual behaviour

• Game crashes while loading, never reaches main menu.

Error log produces the same error across multiple versions of Forge: (14.23.4.2704, 14.23.4.2705, 14.23.4.2765)

Error: net.minecraftforge.fml.common.LoaderExceptionModCrash: Caught exception from MineColonies (minecolonies)
crash-2018-10-02_04.36.08-client.txt

Steps to reproduce the problem

1. Fresh install of .minecraft folder
2. Download Minecraft 1.12.2 from launcher
3. Download Forge 1.12.2-14.23.4.2705-installer-win.exe (recommend version)
4. Download Minecolonies universal and api jar files and place into mods folder
5. Add new launch configuration in launcher that uses Forge version mentioned on step 3
6. Launch game with Forge configuration
7. Game crashes when loading

Huh, it took me a while to find what's probably causing that: don't run API jar on client side unless you are sure you need to do so

Yeah, if you're looking to just play Minecolonies the API jar isn't required, just the universal one.

As nightenom said you only need the minecolonies-universal jar not the API jar.
