I had notice a bit of 1 star comments, so I had to replay to this and say this:
Yes the plugin wasn’t updated for a while and that is a fact, however for me on 1.15.2 the plugin works without any issues, and I don’t see as bad performance issues as some other plugins on spigot community. Coding is not always easy and takes some time to make the code perfect, so please just wait for update and stop saying something without evidence to back it up. From my point of view I am still giving this plugin 5 starts ;) keep it up.
