	return lime.app.Promises.allSettled(futures).then((results) -> {
	// Once all scripts have been registered, THEN validate the imports.
	polymod.hscript._internal.Interp.validateImports();
	if (Polymod.onScriptsLoaded != null) Polymod.onScriptsLoaded();
	return lime.app.Future.withValue(results);
	});

lime.app.Promises only exists in the Funkin Crew fork of lime, which means develop is currently unusable with the official lime haxelib.
