Thanks for the report! This may not be an actual issue with the plugin itself, so we'll have to look into it.

I waited until I started getting complaints about warping/"lag" issue before I installed your plugin.  For what it's worth everyone on the server said it was smoother after the plugin was installed.  I also notice people aren't falling out of the boat anymore and other oddities we were experiencing with only 3 players on the server.
