Don't bother complaining, OP. Bethesda's stance is that what you are experiencing is caused by mods or you are imagining things.
Is that an official one written somewhere?
It's not a complaint, it's feedback so Bethesda can fix it. I sincerely doubt that mods are causing the magic killcams to fail.
I had worse, with the most recent patch, the using magic causes game crash, using bows goes through the enemies, and shouts causes game crash...
.... Ugh. I count myself lucky then.
So....Beth's new patch with new stuff causes new issues, instead of them fixing more existing broken stuff....wow...never would have guessed...thank the stars for Kivan and team. They do 5 times as good as work fixing things, in one tenth the time....makes you wonder sometimes doesn't it

Wasn't surprised - providing feedback so they can fix it, if they are able and have the inclination.
It certainly does. Kivan and the team??? Will I find them on Nexus/Steam Workshop? Can you link me?
