Hello Piranhi,
Yes, if the emitter is still looping and never becomes destroyed this could cause a serious issue. Especially on devices that your project is deployed.
If you could give some reproductions steps of how you have your pawn setup along with the steps you have taken to fix it I can look into a possible feature request. This request would provide a way of updating the user that having your module set to 0 but your emitter still set to 1 will cause issues and would you like to proceed.
