Accidentally destroyed save with mods?
So, I downloaded a couple mods to make things more interesting; more specifically, a few increased enemy variety mods, some that add a few ultra-powerful monsters to specific locations in the game world, one that added a quest to go kill nine specific giant monsters (and its expansion that is connected to Cthulhu somehow-don't ask, haven't done it yet), and a few small mods (unread books glow, dragon priest masks/stones of Barenziah have quest markers, Dragon Souls can be spent on perk points). I also got one that enhanced the appearance of water, but it didn't remove the weird everything's-blue-down-here glitch that I hoped it would so I removed it. So far, everything's been perfectly fine, other than this strange glitch in which some areas on the overworld have invisible walls until I back up five feet and then I can go through, which is a price I am willing to pay to fight Dwarf Dragons and Bloodcrabs while Spiderzilla is battling mammoths in the background.
However, I was looking into the Civil War Overhaul (just wanted to know what it was, wasn't thinking of grabbing it) and the person whomever designed it, who clearly knows enough about the game to finish Bethesda's job for them, made it very clear that downloading or removing any kinds of mods, big or small, without starting a new game, very likely will cause pieces of code to collide and horribly ♥♥♥♥ up everything. Now I'm super paranoid that downloading all those mods mid-playthrough could have messed up my save. I have some saves from before that happened, thankfully, but I accomplished a lot since then (finished a questline, got some cool gear, leveled up a ton, etc.) So, how much did I potentially screw myself over in the long run?
