I suspect her 2nd A time from 930 - 1030 was too short, it was only 1 hour and you are aiming for at least 1.5 hours, probably perhaps getting close to 1hr45 minutes at her age. The first A time in the morning is sometimes shorter for some babies, so I would not always judge all of her A times through the day on how long that one was, kwim? I then think the rest of the day followed on from that 30 minute nap - I was never great at "recovering" at that age myself, I think though that after a 30 minute nap I'd then aim for 1hour of awake time.
Also, about her temperment, just because she is not sleeping at "textbook" times does not mean her temperment is not what it was before. Temperment is really more of a "who she is" not so much a "what she does" - my spirited toddler sleeps like an angel or textbook baby, doesn't mean he's not a spirited child though! She may very well be a textbook baby - but that does not mean that she will fall asleep as soon as she is put in her cot, or sleep as long as we think she is supposed to. She seems to be in a time of transition and change, milestones can affect how babies act, and so on. Does that make sense?
