Extensions not working since new patch

Dear all,
Just installed last week the latest patch.i found out that I have a new launch screen. I launch the game, I have the Gathering Storm ice intro, todo perfect. Then I arrive to the Menu Screen and bam. All leaders from Rise and Fall and Gathering Storms are missing. Impossible to launch my previous saves with Gathering Storm. I have the leaders from the Base Game + additional content (i.e. John Curtis). I have checked my steam add-ons and everything is installed. Any explanations to this and how can I manage to fix it? I posted a 2K ticket so far no answer. Thanks a lot to y all I am desperate to play again!

 

I had a similar issue and it came down to what appears to be the game loading all .xml files in a directory.
So even turning off old mods may not help.
I would recommend, uninstalling. Then manually deleting both main directories And then re-installing.
Seems to be low RAM issues as well but yours sounds more like a config file.

 

Thanks a lot
You recommend uninstall through steam and manually deleting the folders ?

 

Yup
