3rd Party campaigns disappear( again)
 

I'm not connected with the Cloud but do connect with Steam, so here's my problem: every do often ( sometimes,but not always, with a new patch) all my new campaigns disappear from my menu & I have to find the saved versions & reload...why? Is really inconvenient & I tend to lose the spot where my old campaign pilot was,as well.Is there a way to avoid this? How can I periodically saved my campaign histories? Thanks!

There is a file which you had to manually edit to make a campaign seen in game (at least back in April). Each patch over-wrights it with default one. Make a backup of it before patching and after patching restore it from backup.

I do not remember the file name but you can find it if search for any campaign installation instructions from April or May.
