Fail Safely with BuycraftX/Tebex Extension

[austin4195]

Is your feature request related to a problem? Please describe.

Upon booting my server up after having removed the BuycraftX plugin from my server but already copied its server key into the Plan config, when the key was invalid the server spammed many errors until the server crashed. ### I would like to be able to..

Some way for if the BuycraftX key is invalid, It fails safely so that the server does not crash. I was able to fix it by removing the config but some may not know. By adding a fail safely, it can prompt the user in the console that the key is invalid and if the key is not longer active to remove it.

Could you send the error so that I can properly catch it in the code
