Alright, what I'm trying to do is move a location down the path of observers.
They all start out as P12 observers.



Actions:

• Give 1 Protoss Observer owned by Player 7 at 'RIVER 2x2' to Player 8
  
• Give 1 Protoss Observer owned by Player 6 at 'RIVER 2x2' to Player 7
  
• Give 1 Protoss Observer owned by Neutral at 'RIVER 2x2' to Player 6
  
• Center location labeled 'RIVER 2x2' on Protoss Observer owned by Player 6 at 'RIVER 2x2'
  
• Preserve Trigger
  

It works for a while, and then stops here. Why?

Attach map and we'll find out.

Things that could happen:
-somehow misplaced Observer
-Observer was placed for the wrong player
-ai moves the observer

Quick fixing idea:
-make the location 2.5x2.5. That could help (but something else should happen there)

How does it 'stop'?

Does the observer you're pointing at end up being owned by P6, P7, P8 or Nuetral?. Who are the observers on either side owned by.

By rights we should close this, but just in the future remember it


What could be happening, is if maybe another air unit passes by it it could mess them up, or the observers might all be touching each other just enough to push them out of alignment just far enough for your 2x2 location to not be able to reach that one observer.

It was that! Solved.
