First of all feature request:
The ability to list all open/unpaid fines (require a specific permission like demand to see open fines.)
Show fine, to recieve a paper copy of the fine
Options in the config on issuing a fine for the paper to be in the issuers inventory for RP of handing them over.

as for errors:
