I have full cartel vault permissions.

Yesterday I managed to change people's balances without any issues.
Today I wanted to lower one member's balance to then higher another person's balanca.
However when trying to lower anyone's balance, I get the error enclosed.

I'm unable to change anyone's balance anymore for the vault.
Tried with several people, and whenever I try to lower their balance it gives the error.

Tested on both laptop and mobile, same issue/error.

Just tried this myself also. Had the same issue

Replicated here also.

Thank you for the report, this has since been resolved
