Details disappeared (BUG) How do I fix this?

Hey,

I had a blueprint which was based off a C++ class, randomly I noticed that the details tab on the blueprint was no longer visible when it USE TO BEFORE. I was wondering if there is a fix for this?

Previously working (now broken): link text

Recreated blueprint: link text

Things i’ve tried:

  • File>Refresh all nodes inside blueprint
  • Recreated a blueprint with the same C++ parent to see if its C++'s fault. The newly created blueprint worked fine and as expected.
  • Restarted my entire editor and PC
  • Recompiled blueprint and C++

I would hate to have to delete blueprints and recreate them if this bug reappears. In this case the only functionality that was added was just assigning a mesh. Any help would be greatly appreciated!
