And then, i had 3914 euros in hand left. The next day, i came in and i saw that i have -3914 euros in hand.

Please help me ty.

This issue has been resolved, it was simply caused by /levelup taking too much euros. To fix this issue on your account, simply withdraw some money from your bank. We apologize for any inconvenience caused by the slight extra loss in euros.
