What version of the product are you using?
MCore-6.4.1.jar
Factions-2.0.1-MCore-6.4.X.jar
Vault-1.2.25-b320.jar
Gringotts-1.5.2.jar

Do you have an error log of what happened?
see above

Please provide any additional information below.

Just to clarify this is happening with all economic features in factions 2 on our server. Creating a faction, Buying land, creating vaultes, etc.

We've downgraded to Factions 1.8.2 as it doesn't have this issue.

This happens with any economy plugin, its a factions or mcore issue

i have the same exact problem, any fix soon ?

Does this still happen with Gringotts 2.2?
