If you come across a bug, you can submit it to the project bugtracker. If you don't want to make an account on GitHub, you can also find me on Twitter. My handle is handle is @ChrisK91 (but I'm more of a silent user). If you are more of a Reddit user, you can find me either in /r/CubeWorldServer/ or contact me directly via /u/ChrisK91.
My cubeworldforum.org thread can be found here.
