ok apparently it's something that can happen when the language is not english. it will be an easy fix by forcing the conversion

so, basically something causes FIRE to become f\u0131re in the toString on your machine and i have no idea why.
\u0131 is basically the code for ı that gets used in place of i

thank you for looking into the issue
My in game language is english but my computer is in turkish if its needed i can try to see if the issue occurs when i change my computer to english too

i accidentally closed it my bad lol

well uh i switched the computer's language to english and the same thing still occured soo idk

The jar with the supposed fix should be on curse soon.
