Hello everyone!
As the title says, that bug is now no more!
I have also made some other tweaks under the hood, I have removed the SuperVanishAPI and just moved entirely to using the PremiumVanishAPI instead, this solved some class conflict errors.
(Don't worry, SuperVanish users will still have access to the same features as before!)
Hope this is better for you all!
If you discover any other issues with the plugin, please do send me a message or leave a post on the forum with your issue and I'll try my best to assist you.
Change-log:
