Type with FullName `UniverseLib.UniversalBehaviour` is already injected

[SwiTool]

I followed the guide here.

Though, here's my simple code:

        public override void OnApplicationStart()
        {
            Instance = this;
            UniverseLib.Universe.Init(LateInit, LogHandler);
        }

        private static void LateInit()
        {
        }

        private void LogHandler(string log, LogType level)
        {
            switch (level) {
                case LogType.Log:
                    this.LoggerInstance.Msg(log);
                    return;
                case LogType.Warning:
                case LogType.Assert:
                    this.LoggerInstance.Warning(log);
                    return;
                case LogType.Exception:
                case LogType.Error:
                    this.LoggerInstance.Error(log);
                    return;
            }
        }

And the error log

I'm using both UnityExplorer and MelonPreferencesManager. When I don't load my mod, they work just fine, but with my mod, nothing loads at all.

I've read the source code of MelonPreferencesManager but I can't see where i'm doing things wrong.

When I comment out the UniverseLib.Universe.Init() line, the error goes away.

Any idea if bug of misusage ?

I don't know exactly how I fixed this, but surely due to a Clean Build and a typo correction

<!-- IL2CPP References -->

Though, I still have the second error in the log :

Seems like a patching error. I referenced 0Harmony.dll from Game_Data/MelonLoader/0Harmony.dll. I will try with the official Harmony package tonight and see if it solves the problem.

I must say though that I successfully patched some methods with 0Harmony.dll so this shouldn't be a problem in my guess.

I'll do more tests and keep this thread updated.

EDIT: Nah it's the same..
