Emitted entities persist when reloading

In my game there is an emitter successively adding entities to the game, however when I stop and start the game the entities that were emitted last time are still present despite not appearing back at the edit window.

It seems like the default behaviour should be to clear all emitted entities that were present the last time play was pressed as this represents a new session.

That’s simple. Objects are placed on a grid, so when you restart, the objects go back to their assigned places. Emitted objects however do not have a place to go, and remain where they were last sitting.
