I don't know how you haven't fix this yet, because it has been broken since launch, but there is a chest in the opening location. It spawns in the closes small room/barn that is infront of the large building to the left where you spawn in for patrol. It sits on top of a cabinet thing, and it is impossible to open. When you get it, you need to back out and restart the patrol in order for it to despawn.

I can confirm that chest is bugged. Seen it a couple of times, but never been able to open it. I don't think this will be on Bungies priority list though, there are a bunch of other chests to open. It's not the only bugged node either. I've seen a lot of Relic Iron on Mars bugged, but these usually unbug if you leave the area and return.
