I am getting spammed with all sorts of errors such as this

Also, is there anyway to disable that error report? I'd rather if it wasn't shown in general tab... I know it's fun this addon but cannot figure out how to disable LUA errors from showing there

Hi and sorry for the inconvenience. The simplest way to prevent the error from being shown in chat is to install an addon like BugSack, which will capture bugs in a sack for you (and play an annoying sound when it does so, but I believe you can turn that off).

Thank you for submitting the bug, I will take a look and keep you updated here.

Sorry for taking that long to fix this, it just intrigued me to find out when this had broken and I had little spare time the last days.

I also removed the part that apparently warned the player when Evangelism would expire in less than 5 seconds. I don't think this was ever reliable or even functional.
