For some reason certain town names for vaults don't work. I have no idea why so if anyone can help I would love that.

Yeah I'm having the same issue. Specifically:

-While town vaults can be made, they don't reflect the amount of money put in the vault when the town's balance is queried.
-/t deposit doesn't allow deposits from an individual's inventory or their vault into the town's Vault or balance.

So far everything else seems to be working just fine. Does anyone know if there is any intent on Gringotts being updated?

I actually use the nikosgram fork, but for some reason when i rename a nation using townyadmin, it doesnt work with gringotts itself.
