It is possible to create SEPA account using bank account from non-SEPA country, not matching the account country selected when creating the account.
It happened to me recently. My SEPA order to buy BTC was taken by SEPA account where the country of the account was Germany (DE), but the country of the bank account (IBAN) was Georgia.
I think that this is a bug in the BISQ platform and that the IBAN country should be validated against the selected country (limited to SEPA countries only).
