Describe the issue.

When trying to add a reverse patch with Harmony, the game crashes before the splash is shown. Stack trace points to an issue with MelonLoader.Fixes.InstancePatchFix.PatchMethod. It looks like someone made a poor assumption at https://github.com/LavaGang/MelonLoader/blob/master/MelonLoader/Fixes/InstancePatchFix.cs#L17, because the first argument of the target function is a HarmonyMethod, which does not inherit from MethodBase. Unpatching this particular patch prevents the crash from occurring, and reverse patches work as expected.

(Log not attached because relevant stack trace is not captured within MelonLoader's logs, and I can't be bothered to unfix the issue locally just to take a screenshot of the stack trace that appears in the console.)

Did you attach your log file?

No, I could not find a log file at {Game_Directory}\MelonLoader\Latest.log
