For those who didn't know before: couldn't do the hacking stuff on Bluestacks by itself. My Bluestacks emulator is now doing the exact same thing Nox/Jailbroken/Rooted device users are reporting: crashing immediately upon opening. Supposedly Magisk might working I'm testing that out right now.  If you are using one of those for your game right now and haven't grabbed the latest version yet: make sure you've registered your account first so you can save it by logging in on another device.
