Lecky14, I can access the workshop at this time. It's probably a temporary Steam issue, or an isolated Internet issue depending on where each of us live. Try the workshop again later.
Eradem, thanks to a restless night, I think I understand the workshop issue better, and how I ended up still having Active Stealth installed. I'll probably write up a mod purge guide and run it by you for missing details. With as broken as the workshop sub/unsub all links are, and how important it is to get removed server mods cleaned out, I think it will help.
Update: On the server, if I land Mica at the Ark, or whatever, and then walk left, it will not crash with the above error until I get into loading range of the Enhanced Storage shop.
