Since you have problems with more than one plugin, it's a red flag that something's wrong with your server, and like I said - how it changes the map.
The fact that you're the only one who reported such an issue and this plugin alone is currently being used in ~250 servers, speaks for itself.

I can't say for sure what is causing it, but I'm 100% sure it's an external factor and not the plugin itself.
