Everytime I close citra after saving my Pokémon X game my file seems to corrupt, I have evolution fixes and some cheats activated if this is relevant.
In order for us to provide better support, we need to see the log generated by citra. This guide will walk you through how you can obtain the log file: How to Upload the Log File
Disable all your cheats, then restart the emulation. Now see if the issue persists. If it does, upload a log file using the guide that the bot posted above.
