Sadly, I tried downloading quite a few mods before I realized that it was the website having issues and not just a few of those mods. I paused it when I realized but since I missed some of those core mods, it would not download the next batch of 20-50 when the website came back up. I opted to end the collection and start anew. Currently, Vortex is rechecking dependencies and the mods (I assume to avoid double downloading them) but as there are 1200+ in there, it is moving very slowly.
Edit: Yeah, it just finished the check so now cycling back through which is nice to not have to do the previous 1200 again.
