I know Omelette couldn't help me on TESNexus, but I'll try asking one more time over here in hopes that someone else has experienced this and/or knows how to fix it. Or at least knows what type of mods this particular issue would be affected by, because honestly, I have no clue and it's the first I've ever heard about it.
When DR6 is active, attacking with my LMB(Or any mouse button) produces 2 attacks in a single click, as if I double clicked. This is only while standing, I swing once when crouched. Attacks bound to the keyboard work normally. Using my mouse software to make a macro for my side button to press my keyboard-bound attack key works fine, although it's a pretty ghetto work-around that I'd prefer not to use lol. I'd like to know what's causing this and how to fix it, short of reinstalling all my mods if possible. Hell, I don't even know if it's even a mod conflict problem, since I tried starting a new game with no other mods but DR6 active and I still double attacked. Disabling DR6 fixes it. The few seconds before the DR6 scripts initialize inside the game, I can single attack with my LMB.
Edit: Oh, same for casting with the RMB, which normally wouldn't matter, but interferes with UVII's charged casting. So, I guess it happens to every mouse-bound action.
If it helps narrow things down, I tried DR5 and mouse attacks works normally there but after playing it for a bit, I'm going back to DR6(And ghetto binding my side mouse key in the mean time)
My mod/OBSE plugin list:(Feel free to PM me any suggestions/improvements unrelated to the issue if you want. Anything to make me crash less will be appreciated lol)

 Almost all mods were installed through BAIN, so I can provide a BAIN package list too if that'll help. Some mods that won't show up in either list(OMOD install and no esp/esm) are stuff like Darnifed UI, HGEC Body, some EVE HGEC replacers for various mods and Sensual Walks Animations, but I don't think any of those can cause this issue anyway.
Also, if it matters, I've already cleaned all the mods that BOSS said were safe to clean too.
