[Shadows In Rain]

HL.exe hangs with 0 CPU usage, when my module calls MF_UnregisterSPForward. I used tracing via MF_Log to catch dead-end.

void OnPluginsLoaded()
{
	// built-in dependencies
	{
		BuiltIn_RegisterDependency(DEPENDENCY_INITIALIZING);
	}

	// forward plugin_dependencies()
	{
		/* tracer here */
		int fwdid_PluginDependencies = MF_RegisterForward("plugin_dependencies", ET_IGNORE, FP_DONE);
		// good...

		/* tracer here */
		MF_ExecuteForward(fwdid_PluginDependencies);
		// good...

		/* tracer here */ // last tracer that gives output
		MF_UnregisterSPForward(fwdid_PluginDependencies);

		/* tracer here */ // no output
	}

	BuiltIn_ResolveDependency(DEPENDENCY_INITIALIZING);
}

Solved by moving 'MF_UnregisterSPForward' into 'OnAmxxDetach'.
