The company is investigating the situation and is working on a patch to resolve the exploit. Players have reported hacking incidents while playing, with concerns raised about a remote code execution vulnerability. The affected version of the game differs from those on Steam, as it contained an outdated flaw that had already been patched elsewhere.
