What you were expecting to happen, and what actually happened:
I have been doing Stonesong Eyrie for about 7-8 days in a row at faction 500 and prior to the patch the initial room would not summon a Harpy with a 3rd trait (as per the original faction event). Prior to this I cleared the normal 500 run and completed the event when this occurred and this issue was not present in room 1.
How often does this happen? When did it begin happening?
After the patch has landed, the Harpy will summon Harpies all with the third trait in the initial room. All existing attempts prior would summon Harpies without the Harpy Flock (3rd trait).
Steps to make it happen again
Play a delve in Stonesong Eyrie at a reasonable level.
Note the boss room will resummon fully traited Harpies ad infinitum if it has the chance, but the first room did not prior to the new patch. This has been confirmed by other guild members encountering this new issue post 4.7.0.05.
