For some reason every time someone does /kit we get stuck with just the gray opacity background and stuck on the menu with this error in the console..

So this appears and doesn't allow the GUI to work until the plugin is reloaded.

i do /kit add Build (all fine)
/kit items max 10 cooldown 3600 description "Build Kit Every Hour"
It says in chat it has been added so i type /kit to add it to the menu
Here is where the issue is - all i get is a screen with no buttons on so i have to quit the game and rejoin

if i switch to not using the GUI and have the kits show up in chat instead i dont get no errors at all.
