I run ads for a FinTech, still not spending a massive amount, £1k per day. At the moment because it's so early this mostly goes into an ABO testing campaign and CBO scaling was due to launch last week.

But I added two new ad sets into the ABO on 7th August and since then the ENTIRE ACCOUNT just totally imploded. Ads that have been driving £20 CPA for two months suddenly started driving a £250-300 overnight. The new ads were performing terribly. I have since tried to start a new campaign to force a reset, new Ad entities etc but nothing has worked. As far as I can tell tracking is fine (the conversion event can only be done through CAPI, not Browser because of a quirk of their app requiring connection to a third party bank which loses tracking).

Every other metric has stayed consistent - CPM, CTR, CPC, CP1kR. Just the final conversion event.

So, this isn't a post to whine about Meta. It's a call for ideas on what could have caused this sudden implosion. I have been doing this for 12 years and never seen anything like this.

Title is the question really.

Finally received the Dreamchaser campaign expansion, is the Hero expansion (which I’m still trying to get hold of) a requirement to play the campaign well?

Or can I use for example the elves of Lorien, defenders of Gondor starter decks etc etc

(New to the game so don’t judge my lack of custom deck building 😂)
