I had a similar problem: “KILL HEIGHT” node would kill particles and at their death-positions new particles should be created. It worked in Cascade but not in the game-world.
The problem was "USE LOCAL SPACE!"
The emitter with Event-Generator had “use local space” set but the emitter with Event-Receiver did not. It works for me by setting both emitters to “use local space” on or off.
