error on /home set

[HiddenKitten]

This is the same error as #83 which was closed due to no response and a lack of information to reproduce.

It seems to be related to using any character slot except the 1st, and never having logged in to the server using the 1st slot.
while seemingly fully fixed after connecting (and setting a home) using the first character slot (I can now create and list homes now on the 2nd slot), that's not exactly an ideal solution.
this might be more directly as an issue with OpenMod's IUserDataStore, however I'm unfamiliar with OpenMod myself, so I can't say for sure.
additionally, /homes throws an almost identical error to this, in the circumstances this error occurs.
