Bug Report

Type /ver NametagEdit and post the output.

What version of Bukkit/Spigot/PaperSpigot are you using? Type /ver
Spigot-1.19.4

Please explain your issue. How do you trigger it?

I use the MySQL storage method of NametagEdit, and I use the icon %img_:lv0:% from ItemsAdder as a player's prefix. This icon represents a RANK and is displayed in the player's prefix. However, after some time, the server suddenly encounters an error, kicking all players back to my server lobby, and reporting the error message: "The server you were previously on went down, you have been connected to a fallback server." It seems that this issue occurs whenever I use an icon in the prefix with NametagEdit. I have tested it myself, and it appears to be caused by NametagEdit because I don't encounter any errors or get kicked back to the lobby when I don't use icons in the NametagEdit prefixes.

Are there any errors in the console? Please use: https://pastebin.com
