Crash compiling blueprint referenced by Level Sequence while sequence is open

Crash compiling blueprint referenced by Level Sequence while sequence is open

UDN
Description

Compiling a blueprint that is used in a sequence when the blueprint exists on a sublevel will cause a crash if the level sequence is currently open.

Steps to Reproduce
  1. Download the attached project
  2. Open the project
  3. Open Main Map
  4. Open "bpseq" (level sequence)
  5. Click "Edit bpsimple" in the world outliner
  6. Add a print string to the event graph (just something to dirty the blueprint)
  7. Compile

Result: The editor crashes
Expected: Blueprint would compile the changes that were made
