Why is it that when I merge mods via Vortex, the mod files seem to expand or multiply or just become bigger, taking up double the space than they previously did before merging? Is this normal? If it is not normal, is it fixable?

Well, to put in more detail, I just finished heavily modding Skyrim with workshop mods, and then I moved on here, Nexus, to download a bundle of mods. So then I started installing/ testing mods, and the first mod I tested caused CTD after logo, so then I uninstalled, moved to the next, and I had the same problem, so I did this 20 times more or less, and it turns out that any mod I try using from Nexus causes me a CTD, and I really need help with this.
