I'm going to take a minute to gush a bit.
These ruins look amazing. Maybe it's just because I found them, but I think this is way cooler than anything else Frontier has put in the game.
The Obelisks glowing as you approach them. The pillars bursting out of the ground. These feel way more "alive" than the barnacles.
It's just awesome man.
I totally agree. I'm there now and I can't stop going around the Ruins.
On a second note, I feel very confident in declaring that those "mysterious things" in the patch notes are almost surely these nice mysterious artifacts we are finding: Orb, Totem, Relic and fellas. From the patch notes it was very clear that they are scoopable items, and that there was an issue with them becoming a simple canister after jettisoning (a similar "glitch" was/is happening with Meta Alloys).
