I saw some event lvl 2 that are full of all wave ship.
A person commented that they are using a ship with a cloaking module to force all the waves to be there and so when someone enters they die, since they would be put with a point, and would not be able to escape damage from 40 ships.
You should be looking at your probe scanner for sites (Alt-P in space). The ones on the Overview have already been activated; you’ll find the unactivated ones with the activated ones in the scanner window.
You can undock the scanner window from the map and close the map.
