What Happened To Ghost?

[Hogfather]

Is this a bug or did the distance from enemies to you before your shade cloaks you get shortened? Also I was hiding by a door where the enemy couldn't see me but I could see it (thank you 3rd person view) and I didn't cloak until it came through the door (right beside me, almost walked into me). That one didn't see me so I dispatched it quickly but there was another one maybe 20 meters on the other side of the door walking toward me so I sat and hid around the corner untill I should have cloaked. Assuming I was going to cloak I walked out behind it and didn't cloak.... The ancient healer turned around and saw me (still not cloaking....) and threw his arm spike at me....

 

I am really confused. Before update 7.11.0 I would cloak all the time and had no problem running around having fun? All I want to know is what happened? I don't remember reading anything in the updates about the Shade. Did I miss something or is this a bug?

 

 Thank you for your help.
