At each timer's end, a random event is launched and removed from the event pool.
But it seems that when this pool is empty, it is not reset, so no event happen anymore.

Exemple

If i deactivate all events but one, only one event will be launched but the next event cannot be launched because the pool is empty :
This message appears in the log :

This occurs when activating more than one event too.

Thanks for opening this issue!
