1. Open the attached project
2. Try to open ThirdPersonBP/Blueprints/TestBP or place it in the level
3. Editor crash
(Steps to create the repro project)
1. Create a new ThirdPerson Project
2. Create a new child of Mannequin/Animations/ThirdPerson_AnimBP (ThirdPerson_AnimBP_Child)
3. Add a new character BP(testBP) in ThirdPersonBP/Blueprints, then edit it to use SK_Mannequin mesh, with ThirdPerson_AnimBP_Child animBP.
4. Save the added files
5. Open ThirdPerson_AnimBP_Child and reparent it from ThirdPerson_AnimBP to AnimInstance. This causes compile error but save the AnimBP anyway
6. Close the project then reopen
7. Now opening TestBP or trying to place it causes this crash
