Description

I understand that this is not something you're intended to be able to do (Montages aren't used this way), but we should bar the user from inserting a montage into this variable slot.

Crash occurs when you attempt to enter a Montage into Sequence field of a Play Node details panel inside of the AnimGraph.

Error message:

Steps to Reproduce

1. Create a Third Person Template project
2. Create an AnimMontage based off of the Mannequin Skeleton
3. Drop an AnimSequence into the Montage
4. Save
5. Open ThirdPerson_AnimBP
6. Right Click in the Anim Graph and add Play node for the idle animation
7. Under the details panel for the Play Node, select the dropdown for "Sequence"
8. Select the AnimMontage you created earlier
9. Plug the Play node into the Final Animation Pose
10. Compile

Result: Crash
Expected: Editor doesn't allow me to enter a Montage as the Sequence variable in a Play node
