If you generated the map then look in your generated worlds folder for the map in question. There will be a text file in the folder called prefabs. Open that file and you can see what POI's were generated without having to go all over the map. The listing also gives you the coordinates of the POI on the map. The path to the generated worlds folder is as follows (Windows 10) Users\username\AppData\Roaming\7DaysToDie\GeneratedWorlds\Mapname. You will need to set your view in file explorer to "show hidden items" in order to see the appdata folder. If you want to look for a particular POI in the Prefab list then use ctrl F and this will open a search dialogue box. Type in the name of the prefab and then it will take you to the first one on the list. I use this to verify that the Research Facility gets generated in every map I create. Hint: for a list of darkness falls prefabs just type "DF" and then press enter. It will show you all the Darkness Falls prefabs.
