Wormholes

So I entered a C1 wormhole and warped to Perimeter Camp. One of my favs because of the large amount of frigates. Here's what every site tells me about Perimeter Camp, and has always been right.

Initial Group
2x Sentries (Sirius)
2x Frigates (Emergent Watchmen) [nos] TRIGGER
4x Frigates (Emergent Patroller)

Reinforcements Wave 1
3x Frigates (Emergent Watchman) [nos]
3x Frigates (Emergent Patroller)
1x Cruisers (Awakened Patroller) TRIGGER

Reinforcements Wave 2
2x Frigates (Emergent Patroller)
2x Cruisers (Awakened Patroller)
1x Cruisers (Awakened Watchman) [nos]

Today? Both Perimeter Camp anoms I did, I had to warp out of and back to frequently (Drake), because the Initial group had an Awakened Patroller with Nos. In the first room I tried killing the nos cruiser after killing the 2 towers, and one of the nos frigates. After the cruiser died, more enemies warped in. Not even the wave of sleepers that warped in obeyed the usual trigger rules.

In the second room, I killed the 2 frigates and that was the trigger (as the list says it should be.)

What happened? Did CCP change the anoms overnight?

Edit: And damn. not a single Melted Nanoribbon. An hour between the 2 rooms and salvaging. That wormhole is not only buggy, but I feel jipped. :0
