While we work hard to make sure that MCC Island is as good as we can possibly make it, the server is also in beta for a reason. Bugs may appear from time to time as we add new features, tweak existing systems or just as part of the development process.
If you see a bug, please report it on our forums.
Make sure to run the /bugreport command when you see an issue and add the link provided to your report so that we can get a better understanding of what's gone wrong and have a better chance at fixing it!
