I dont want to disagree with the best scripter i know.
But when i put event on map "a flower"
When i pick up self switch a goes ON.
Wait 200 = 10 sec
Self switch a OFF
Flower apeares on map again.
If i pick flower, wait 8 sec, leave map, come back, 10 sec later flower spawns.
So if i pick flower, wait 8 sec, leave map for 3 hours, come back, i wait 10 sec and flower comes back.
So sadly i have to disagree, event does not disapear. Last command will be executed when u enter the map.
