I keep driving back and forth across the Guardian Monument dropping the required cargo from SRV, but nothing happens...
Okay... I've tried a different Guardian site, and... it worked.
Maybe because that area around the first site was not flat... (?)
Thanks for all your efforts and time to respond.
You do not remember correctly.If I remember correctly, it is the sites that give you weapon blueprints that need the key, not the relic...
No. Untrue.You should get a message when you pick up the key at the beacon. That message lists a system where the key belongs to. You can only activate one site with the key.
