Bug/Issue Fatal Error: assert failure in file "/data/starbound/starbound/source/core/StarList.hpp"

I am unsure as to whether or not this is mod related so I thought I'd gain some insight here (hopefully) then follow up with the proper mod developer if necessary.

This is a server log and when it happens whoever is online gets teleported to their ship or sometimes disconnected due to a client connection error. I've not gotten that exact message but I will next time it happens.

I can sometime recreate it by just exploring in one direction of a planet until this happens. There is no freezing or crashing of the client just the server. The server is a dedicated hosted server via Multiplay.
