We've been experiencing a persistent error for one member on our server where their town randomly deletes. They deposit enough money into their bank to sustain upkeep for plenty of days, and the console shows the town successfully paying their upkeep. However, their town randomly deletes after an unknown period of time.

We're unsure what the error could be, as there is only one user experiencing this issue and there is nothing logged in the console of this event happening for us to look into and fix, so we're left with nothing. This has been happening over a duration of 3 days, and continues to delete only their town.

Thank you in advance.

What is the exact name of the town and what is your economy plugin?
…

The exact name of the town is Reykjavík
The economy plugin we're using is Vault

Use /vault-info to show me the economy plugin.

Use /t {insertnamehere to show me the name of the town.

Information sent from running /vault-info

We're waiting for the member to recreate their town and will submit that in due course

If the town name has used Unicode characters in the name of their town, ess
eco doesn't make accounts named with characters that cannot be used in
Minecraft account names.

Change economy plugins or use towny's regex settings to prevent Unicode
characters being used.
…

Okay, thank you for this. Do you know what economy plugin works with Towny and will prevent this from happening in the future? We're looking to allow towns with certain special characters / unicode characters to form.

I would recommend using TheNewEconomy in combination with Vaultunlocked

We'll definitely look into this in the future, thanks for this. In the meantime, what do we need to change the regex settings to in Towny for ess eco to support it? I've looked at TNE and installed it on our server just now, but it looks completely different and I don't want to change the gameplay for players if I don't have to
