*There is a bug in here, but it may be in Interface.*
The sphere entities have a lifetime of 60s.
The first time the script is run, each click fires one clickReleaseOnEntity event.
If the entities expire (lifetime is reached), and the script is rerun a second time,
each click will fire two clickReleaseOnEntity events.
If this is repeated (waiting for expiration each time), then
the N-th repetition will fire N clickReleaseOnEntity events.
Note that each entity, across runs, has a unique uuid, as expected.
