I got it to work, but...
While importing settings from MO2, vortex creates a new mod download folder in Appdata (where it copies all packed mods) then throws every mod and plugin in the game directory. This results in a lot of lost space on the C: drive. (20gigs for FNV) Uninstalling vortex does not give an option to remove this data and leaves everything there. Instead you need to know in advance how to remove all mods and purge them from your system. No info about this is given beforehand, so you are left with deleting everything by hand and reinstalling your game to get your precious space back. Not really user friendly.
Not having a choice where the data is stored or having the option to point to a mod dir on another drive when installing vortex is just not working for me. I hope things will improve in the future, but I cannot endorse vortex at this moment.
