Apparently mods will not work in the foreseeable future, at least from the Nexus. And the in-game manager surprised me in a very bad way: only complete garbage appeared in 8 days. Are there really any serious technical problems?
Is there any solution to returning to patch 6?
In steam, you click on properties, select "betas" and then select the patch 6 option in the dropdown box. It will reinstall patch 6/hotfix 25 for you.
Beware that many mods have upgraded to patch 7 already, so if you install something, check if you need to use old file also. ImprovedUI for instance is an imortant mod where the latest version will not work on 6 anymore, so you have to take an older file there.
