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

Navigate to Editor Preferences->Experimental and enable Environment Querying System
Create a new EQS Test
Add a Points on Grid test to the EQS
Save it
Create a new blueprint based on EQS Testing Pawn
Place it in the level
In the EQS Testing Pawn's details panel, set Query Template to the EQS you created

Alternate Repro:
