Vehicle Anim Blueprint: Montage node doesn't exist in package build

I have a vehicle animation Blueprint with a montage slot.

In the editor the montage slot works as expected.

In a packaged build, the slot doesn’t exist.

Hey there,

There was a fix for this in 5.4, but you should be able to backport the change. Your team has perforce access, so you can try CL: 31526895, which is a one-line fix for the Wheel Handler node.
