When Service Desk is installed, it provides some new Issue Types to work with as compared to JIRA Core/Software. Some of these Issue Types are Incident, Problem, Change, Fault, Service Request, IT Help, etc and each of these uses a brand new Issue icon.
However, if you change, edit, or delete these issues or their icons, you seemingly cannot choose them again! I changed an icon for the new default Problem issue type, however if I try to change that Issue's icon again, the original icon isn't available for selection ... it's only the default JIRA Core icon set.
So where are the Service Desk brought issue icons located? So that I can save them from the server and upload them manually to an issue type.
