Moved Private Server to new PC and now can't reconnect to old characters

(I'm not sure if this qualifies as a bug report, since this my be by design?)

I have started a 2x2 server cluster for Atlas, but as this is too much to run on my laptop while playing I decided to fix up a PC and move the servers over. The servers successfully moved while keeping all of the saved data, but I was unable to reconnect to the server. Since our characters were no longer on the home server, I edited the servergrid.json and made the map with our bodies the home server so I could connect directly. However, when I joined it still prompted me to create a new character (I'm still playing the game with the same laptop), so I made one to see if our bodies were still there and it turns out yes they are.

I am at my wits end trying to understand why it won't let me rejoin as my character. Has anybody experienced a similar issue and found a fix?
