Description

The editor is crashing when attempting to add a query template to an EQS Testing Pawn. This only occurs on Mac.

Found in 4.15. Unable to reproduce in 4.14.3. This is a regression.

Steps to Reproduce
  1. Open the editor (On a Mac)
  2. Navigate to Editor Preferences->Experimental and enable Environment Querying System
  3. Create a new EQS Test
  4. Add a Points on Grid test to the EQS
  5. Save it
  6. Create a new blueprint based on EQS Testing Pawn
  7. Place it in the level
  8. In the EQS Testing Pawn's details panel, set Query Template to the EQS you created

Alternate Repro:

  1. Open the attached project
  2. Select TestingPawn
  3. Set the Query Template on the TestingPawn to EQSTest

Result: Editor crashes

Expected: No crash would occur
