I haven't been playing skyrim much lately and I haven't been following the forums so I apologize if this has been mentioned already.

With the new patch and the (awesome) new killcams, I've noticed that when you fire an arrow on a killshot the target takes zero damage but dies on the second shot. It could be a glitch or a problem with my mods, I'm not sure.

The mods I'm running are:

Stones of Barenziah Quest Markers
Brand-Shei Prison Fix
Dwarven Scrap Renamed
Dwemer Rifle
Explosive Arrows (not using them atm) As an aside, if you're looking into a killing spree to blow off steam these are freaking awesome, just don't save your game because you'll kill EVERYTHING. I recommend using them on your first trip to Solitude for some awesome fun. wink wink.
GoldenVendors (10x vendor gold)
Increased Bounty Rewards
KillThemGenerals
Waterbreathing Breathless Emerge
Enchanting Freedom
More Map Markers
Sleep For 5x Exp
JoOs Mass Lightning
Proudspire Manor Expansion V2.
Uncapped Perks - Combat + Stealth
Uncapped Perks - Magic

I'm also running the community uncapper with skse and if this is not a glitch with the current patch I'm assuming this is the problem.

I have something similar, but with melee kills as well as ranged kills.

In my case, I can activate the finisher 10 times and the monster won't die. D:
