Compatibility issue with ShellProtector on optimiser versions over 3.8.0

[arianwen27]

On optimiser versions 3.9.0 and higher, d4rk fully brakes the decryption of shell protector. Staying on 3.8.0 works correctly. I know ShellProtector isn't managed by this project but I might as well mention the compatibility issue with the latest optimiser versions.

I'm having to stay on 3.8.0 for my avatars that use ShellProtector until hopefully something can be figured out. The versions of ShellProtector doesn't seem to make a difference, it's only when optimiser version 3.9.0 or higher is used that decryption fails and the texture remains broken.
