 * Hello! As you can see, sometimes I receive this error:
 * [https://prnt.sc/wRhA0rUhXBZ2](https://prnt.sc/wRhA0rUhXBZ2)
 * The “custom_data” seems to be empty sometimes [https://prnt.sc/gZchm1pDmR1Z](https://prnt.sc/gZchm1pDmR1Z)
 * I posted here with the hope that this bug will be fixed in the next update.
 * Thanks!

 * Hi Syncr0n, I hope you had a good weekend.
 * Thanks for reaching out to us.
   I have passed this information on to the development
   team and they are investigating. The plan is to make some adjustments to that
   function and put it in the next release or the one after that hopfully.
 * If I have an update on this, I will message you here.
 * In the meantime, if there is anything else, don’t hesitate to let us know.
 * All the best.

 * Hi Syncr0n,
 * We recently released a new version of Pixel Cat that looks to fix the error you
   were getting. Maybe when you have a moment you can update to the latest version
   and let us know if the error messages stop now.
 * Thanks and all the best.
