I found that conjuring atronach doesn't work every time after the newest patch. I used to be able to point any direction and cast conjuration. But now I usually fail to conjure, while I can still hear the sound, but I don't see the blue glow and no magic is consumed. It seems like you have to cast in certain direction, which was not a problem, at least I don't remember how it mattered before this patch.
Anyone have same problem? Is this a new bug?

Did you by any chance recently take the Atronach Stone? There's a bug with it.

Check if you have any spell absorption effects on you. There's a bug where you absorb your conjurations.

Yeah, I did activate Atronach Stone and it was my first time checking on that stone. So can I wash this bug away by activating some other stones?

Yeah, as long as you don't have spell absorption effects, your conjurations will work normally.

Great, thanks a lot.

hmm... should be possible to rectify this through the creation kit...

There is already a mod for this:

Nice one. Minutes ago I found for myself too that it was the spells, been left unchecked and allowed absorption/reflection. The Atronach Stone and the homonymous Restoration perk were simply responding to what they were being "told to".
