GPU particles not colliding in-game in all my existing maps

I’ve got a simple particle system which pushes GPU particles (with Collision) down onto a basic plane. In all cases, the particles bounce in editor. In my existing maps, made in 4.0 and copied to 4.2, the particles will not bounce when playing in game, even when I replace the ground with the exact same simple plane. In all new maps I create, the particles successfully bounce in game. I’ve been diligent to eliminate any other possible affectors, going so far as to strip my existing maps down to only the plane and the emitter.

What has changed? What can I do to my existing maps to make them work with GPU collisions?
