@Hime Sorry but it is not a solution at all. Your devs spend 3 months to implement an anti cheat that was already bypassed over a year ago. That time was completely wasted. If gameguard is bypassed it can't block or monitor anything.
Why are you not using a proper anti cheat like Easy Anti Cheat? The game is already on UE4. Implementing that shouldn't be an issue and there is no known bypasser yet. Or alteast enable heartbeat on gameguard so that you can't bypass it anymore. Even though that still won't fix all the issues with it.
It almost feels like your doing this on purpose. You can't tell me the devs didn't knew that gameguard was already bypassable.
