After server restarts people can use tp commands in monuments but if the plugin is reloaded it works fine.

I also see now where the width of some monuments such as the Airfield have a size of (0, 0, 0).  Adding a defaultmonumentsize config option and will check into the loading issue.

Merged post

I was not able to duplicate the error.  However, like I said, some monuments seem to have a game size (extent) of 0.

Alright thanks for taking your time looking into it anyways 

A new config for DefaultMonumentSize has been added in case the returned value from finding the monuments is 0.  You may need to adjust to your preference for distance from the center of a monument.  At some point it might be possible to add different defaults for different monuments with no correct size given.
