• Click More Options.
• Under “JVM Arguments,” look for -Xmx4G (or another value).
• Increase the value (-Xmx6G or -Xmx8G). Avoid going above half of your total system RAM.

2. Check for Mod Conflicts

Some mods may conflict with MineColonies. Check for known conflicts by:

• Removing any recently added mods.
• Checking the MineColonies GitHub Issues page for reported conflicts.
• Disabling mods one by one and testing after each.

6. Use a Different Blueprint

If the crash happens with a specific build type:

• Try confirming a different building.

7. Update Java and Graphics Drivers

Ensure your Java and GPU drivers are up to date:

• Update Java
  • Download the latest Java 17 from Adoptium.
