Using 10 threads is still not fixing it for me... is there something particularly weird with the Skyrim SSE Legacy of the Dragonborn mod? My download speed (even at 1 thread) would shoot up to download all the other mods I've decided I want, but for this mod in particular, even after going premium, bumping up to 10 threads, re-starting the download from scratch, and restarting vortex multiple times, I'm consistently not managing to hit even 50 KB/sec.
Have you tried to download the problem mod manually?
Yes, but I find when vortex works, it goes much faster than manual downloads through a browser do for me. I may just do that instead, but downloading a 1gig+ mod is gonna be rough.
