I didn't use it- just woke up and it had lost 60%. Any common culprits or reasons?

Just finished a trip in 30* and despite a 20f hammock gear quilt and wearing good layers I was cold. I’m always cold. Rather than buy another bag just for cold temps (I rarely camp in 30s), I’m looking for a very compact second bag that ca either serve as my main bag if it’s really hot at night but can also be a supplement for when I do camp in cold.

Any recs? More worried about volume than weight, but this is UL so grams matter too.
