Hi ,

Thank you for the project, many people tried to pin down the problem, but we had no stable repro steps so far:)

Cheers,
M

You’re welcome, glad to be of some help ^^.

For the record, I’m having the same issue.

I have a ScrollList Box defined in my parent class.
I then set this ScrollList Box to be a listbox in my class deriving from the parent class. - If I don’t compile the derived class before running, the variable from the parent class will be out of scope, and the editor will crash.

Crash report:

Unknown exception - code 00000001 (first/second chance not available)

Hi Pequeno,

Thank you for this information. I just checked on the status and UE-13859 has been marked as fixed in 4.8.
