Fix it with Stella · Gaming

Modpack crashes on launch? The log knows why.

An instant crash is almost always the wrong Java version, too little RAM, or one conflicting mod. Stella reads the crash report — the whole thing — installs the Java your pack actually needs, sets the allocation, and pulls the mod that's breaking the load.

You: My CurseForge modpack crashes with 'exit code 1' the second I hit play. Read the crash report and fix it. Stella: Wrong Java and one conflicting overlay mod. I'll install the Java the pack wants and pull the conflict. You: Then launch it. Stella: Java 17 is pointed at the launcher, RAM is set, pack is up. You're in.

On this problem

What Stella actually does.

  • Opens the crash-reports folder and reads the actual error, stack trace and all
  • Installs the exact Java version your pack needs and points the launcher at it
  • Sets a sane RAM allocation for the pack size
  • Finds the conflicting mod, removes or updates it, and relaunches to confirm
