Class defaults' details page is blank

I can’t access PlayerController classes’ class defaults settings via details tab in blueprints (details tab is just blank).
On very infrequent, random occasions, details tab may show up, but then go back to being blank after navigating away from it.
I’m on ue4.8 preview 3.

Hi unrealChris,

Thanks for report! We are aware of this issue in 4.8 Preview 3 (UE-15844), and issue has already been fixed internally. fix should appear in next 4.8 release, whether another preview or official release. Let us know if you continue to see this problem after that. Thanks!

Unfortunately not at moment. There are plans to make them public, but there’s not specific time frame for that right now. For now, we mostly post numbers so that we can easily look them up if new people have questions or if we get an update to bug report itself.

Thank you.
I checked to see if it was a know bug, but couldn’t find it.
Are bug numbers like (UE-15844) useful to users like me to check on progress or is it for internal purposes?
Is there a place that we can look up bugs besides Unreal Engine 4.8 Preview - Announcements - Epic Developer Community Forums
