Urgent Unity Puzzle Fix Needed

I have a mobile multiplayer tile-matching game built with Unity that raises security warnings. The reports point to broken data-encryption routines and a couple of code vulnerabilities that need to be closed before I can submit the next update.

At the same time, every time the AI “thinks”, the on-screen tokens flicker visibly. Players notice it and assume the app is hanging, so I need that visual glitch ironed out right away.

Here’s what I need from you:
• Review and harden the data-encryption flow and remove any code vulnerabilities now triggering the warnings.
• Eliminate the token flicker during AI computation without adding noticeable lag.
• Provide a short summary of the fixes, plus the edited source files or patch so I can merge straight into main. Also, once you fixed the detail from above, you will be in charge of submitting the game.

The project is time-sensitive, so if you have recent Unity mobile experience and can jump straight into a Puzzle-genre codebase, let’s get started.

Please, take a look on my game for better understanding: https://play.google.com/store/apps/details?id=com.tecshield.swappy
