Harmony.CreateAndPatchAll(typeof(ExclusiveHealthPatch)); Compile your mod to a DLL. Place it in the Mods folder. But because you are patching an internal method, you must also set <AllowUnsafeBlocks>true</AllowUnsafeBlocks> in your project file and ensure Harmony has InternalsVisibleTo access (or use [assembly: IgnoresAccessChecksTo("VintagestoryLib")] ).

Using an exclusive patch directly inside VintagestoryLib.dll 's TemporalRift class, CaveDweller rewrote the entire instability algorithm, adding realistic decay functions and server-wide temporal storms. The result? A mod that was praised for its innovation but criticized for causing memory leaks on dedicated servers due to improper garbage collection handling in the patched method.
