I’d guess Epic is using Jira(like a lot of other companies) for BugTracking. Is there any consideration of making a mirrored public Jira?
Embarcadero does this for their products, for example. So you can report a Bug in Jira, it gets a mirrored entry to their internal Tracker. And once done, they mirror the result back to the public one.
This allows proper discussion in a detailed Ticket.
I use Unreal only for sparetimeprojects but work at a NonGaming-Softwarecompany. We use Jira, and the options for organization and filtering are great.
