When you hit play with a groom in the scene, the engine crashes
Additional notes: First tried adding it to a skeletal mesh through a character blueprint. Engine crashes. Engine doesn't crash if played in simulate mode. Added hair material to a cube, engine runs fine. Used "Convert to Geometry" function in xGen, added raw geo with hair material, runs fine.
Created a new level called "BlankTest01". Added a cube for the ground and scaled it appropriately. Added a simple marble material to the ground. Added a point light. Added a groom (.abc) file into the scene. No gamemode override, gamemode set to "GameModeBase" from the default game proejct. Hit "playtest" button. Engine crashes
