Since the recent Vortex program update released around 3-21-22, I have installed 5 new mods, and Vortex did not copy some or none of the the files in the mod archive over to the game folders.
I checked the plugns list in vortex after each install, and the plugin is not there (when it should be).
I open my mod archive in one window, and the game folder (steamapps\falllout 4\..) in another window side by side and compared each file in the mod package to the target location in the game folders. In the case of all 5 Vortex did not copy the files to the target location. But the mod list in Vortex says it did install them.
I go thru the mod packages and manually copy the files where they are supposed to be in the game folders.
Restart Vortex and it scans the folders, then it will show the plugins in the plugins list. Running the game verifies those mods functional.
I have installed 22 mods before the Vortex 3-21-22 program update with no issue of any kind. Vortex installed the mods accurately and ran any associated fomods connected with them.
So whatever you guys changed on that update near March 21, 2022 has screwed up Vortex from operating correctly, at least on my pc and the pc of a close friend.
Please look into this, find the issue, fix it and issue a hotfix for it. Not everybody knows how to install mods manually, tweak ini and xml files and for that matter navigate their pc with window's file manager.
This may be relevant.
My steam application and all games and programs including Vortex are not installed on my C: drive. They are installed on my auxiliary SSD labeled D:.
Does your last update default to install folders located on C: drive?
