A while ago I noticed that certain Notrium mods were getting very hard to find, so I archived everything I could find. I now have a 107MB .7z file containing the latest Notrium installer and the latest version of every mod I am aware of, including Werivar & Werivar Expansion.
Since dropbox is helpfully hosting it for me, this link should stay live for the foreseeable future, but everyone please download and store this anyway as a backup. If anyone can point me to another major mod or updated version, please do so and I will add it.
I may also create a torrent of this file if I think there's enough interest.
