Unhandled exceptions on server when adding/removing waypoints

Description

Was playing on a test server for the pre-release, it is essentially vanilla. And I get kicked off the server for triggering a unhandled exception whenever I would create or delete a waypoint on the map.

I do have Icelandic language on my client, and the admin was kind enough to even manually add the language to the server in hopes of it fixing things (since it did solve other language related issues on another of their servers that th3essentials caused whenever I would use it's features). That fix did not solve the issue with the waypoints. And we kind of excluded th3essentials as the cause in this case.

Admin of server listed these mods:

just 4 mods are here livemap, playerlist, th3essentials and vsserverpanel

On my end, only mod I had enabled was HUD Clock, can hardly call that playing modded.

I did get the log from the admin

I really think there really should be some handler that just defaults to the English if it fails to look up the language... be it the game or mods...

How to reproduce

Have client set to use a language not previously listed, so it is manually added. I use Icelandic. (could just copy en.json and turn it into is.json for that effect)
Join server
Create/Delete a waypoint on the map
