This mod is an experimental fix that will be rolled into the Starfield Community Patch if it is successful. 

A common problem I've seen others report is for the "Power from Beyond" quest to be started (either from Vladimir or by stumbling on the planet) but the target planet lacks an "Anomaly Location" marker to land at. It's not entirely clear how the game gets into this state, but the Anomaly-related aliases on this quests are option (and probably shouldn't be). 

This fix will do the following thing as soon as you load the game:

• Get a list of all known temple locations.
• Check each instance of "Power from Beyond" (there are 6 of them) to see if the quest is running but the Anomaly Map Marker is missing. 
• If the marker is missing, it does a search for a new planet to put the temple on, excluding all those that already have temples (in my testing, the same planet can be picked twice somehow!). 
• It then simulates the startup of "Power from Beyond" and check that a valid AnomalyLocation and AnomalyMapMarker fill in. If not, it adds that planet to the exclusion list and tries again. 
• When a valid planet is found, the original "Power from Beyond" quest is updated by forcing the locations to match the fixed ones. 
• The objective is refreshed (if visible) to point to a valid planet. 
  

Once this fix has applied the rest of the mission appears to self-heal. Once you arrive in orbit or land at the map marker, a temple is spawn and all the internal data structures are aligned to the new location. 

Backup your save before applying this fix. This is an experimental fix as I've only had two saved games where this bug occurs to test on. 


How to Install

Vortex or Mod Organizer 2 is recommended to prevent user error on installation. If you prefer to install manually, follow the steps below.

• Extract the content of the downloaded ZIP file directly into the game folder (Next to Starfield.exe).
• Ensure that inside the Data folder you now have a file called PFB-TempleMarkerFix.esm, if not you installed it wrong. 
• In %localappdata%\Starfield create or open your plugins.txt file and add "*PFB-TempleMarkerFix.esm" to the last line. (In Vortex, you can do this by using the "Open Game Application Data" button on the Mods toolbar.)
• Load the game. A message in the top-right of the screen will confirm the fix is finished. Additional pop-ups will appear for each fix applied.
  

Feedback

Please do let me know if the comment if this worked for you.

If you're having problems please exit the game and go to your StarfieldCustom.ini to add the following section.
[Papyrus]
bEnableLogging=1
bEnableTrace=1
bLoadDebugInformation = 1

Now reload your save again. This time the fix will write a log file. You can find it in your documents folder under My Games\Starfield\Logs\Script\User\StarfieldCommunityPatch.0.log an example of the output is below.
