Hi croxis, I hope you're having a nice day :D. 👍 to your awesome plugin that you have here and the epic support that you give :).

I ran a new Tekkit 3.1.3 server (CB 1.2.5R5 is the latest) with a few other plugins and plugged in Lift 30 (which claimed to support pre-1.4 servers, such as Tekkit). And I keep having this message spam over and over as soon as I log in:-

I am grateful for your help.
And if you need anyone to help with webpage management or programming/testing for development, I'll be happy to help.

Fixed for version 31
