P: Undo History Brush

I'm getting this too. Very frustrating. I just spent an hour on Adobe Live Support explaining it to them. Finally got them to understand my problem (after sharing my screen and showing them multiple times) and got a 'I'll check that and get back to you' response. I guess we'll wait and see...

Alignment to a selection / marquee just stopped working again. No change in behavior and in the same PSD. I can no longer align by a selection / marquee. Objects always center to an artboard... Sad day.

When will this be fixed?

I've just discovered, it is fixed if trying to align multiple objects to a selection, but not if you are aligning a single object to a selection.

Could you make a fix for this please Adobe?

I am using windows 10, and yes, i. Working on mulriple artboards

Updated but not fixed yet. I was using Mac.

I also have updated to Release 2051114.r.301 x64 and it's not fixed either. It's still aligning to the artboard instead of to the selection. When is this going to be fixed properly?

Version 20151114.r.301 x64
I'm running windows 8.1

Layer alignment aligns layer to Artboard when using Artboards and will not align to Selection. The layer aligns to the artboard even when objects are selected.
I'm using the latest Photoshop CC 2015.1 Release 2051114.r.301 x64

Really? What is your version no? Mine is 20151114.r.301 x64
