I think the sidequests mentioned here for 1.18 are complete. I was everywhere atleast once, where you could find an NPC besides eagles nest and Camp Riversmeet. I will go there if i really have the mood for it. If there is a following quest e.g. for rustproof, i havn't found it yet. This patch was alot of running and im without help of a support teleporter.
I'm a bit of exhausted after running around 30h+. All in all the patch was bad. The new outposts are small and probably created in 1 day, just to say we got new areas. Only a few sidequests implemented, too. But i get offtopic here.
