So when I used the /buyraid command in-game the menu pops up but it doesn't allow me to click it. It doesn't even give me the cursor to even attempt to click it and I can't despawn it from my gui without restarting the plugin itself.

Thank you for you time!

press enter then click it. you can close it by clicking the X. if you don't have prices set above 0 then you won't be able to buy any of them by clicking them
