GenP doesn’t need an update for this.
Monkrus releases are essentially prepatched using the same underlying methods, just packaged as standalone installers. Because of that, the setup and install environment can differ slightly compared to doing a normal install and patching it yourself with GenP.
So a repack working doesn’t confirm an issue with GenP, it usually points more toward a difference in setup or configuration on your side rather than a problem with the patching itself.
