I created 4 enemy encouters, then erased them, then created 4 more. All 8 enemy encounters where present with the exception of a clich on the deleted 4. The deleted 4 should only have shown up after a pop window. The later 4 showed up after popwindow just as planned. The 4 where already on the map, when there wasn't supposed to show up until after the popup window.
After deleting the 4 enemy encounters i noticed they where still on the map. With them erased from the story line editor, i created 4 more encounters. This made 8 encounters.
It did not behave as expected, but i do relize this can be seen as a fetcher.
