I also moved a group of (approx. 40) keywords out of one ad group and made a new ad group to put them in. I did this same process in two different campaigns (one was the campaign that I condensed the ad groups in and another separate campaign). I did slightly modify the ads associated with the respective ad group to better match what I had in mind by making the above changes.
All of the ad groups and keywords associated with the keywords have minimal impact on the campaigns as a whole in terms of overall clicks and impressions.
My question is this...Could making these changes, all in one day, have an effect on the entire campaign and account? It seems very coincidental that the DAY AFTER I made these changes, our clicks dropped by just over 50% from the day in which I made these changes. Our impressions dropped as well, though not as great as the clicks (around 30%).
I hope this makes sense I thank you in advance for your comments.
So make sure that's the only thing that happened that day, check your web stats, make sure everything else looked normal, etc.

A quick answer, as another possibility:
It is important to remember that any new or edited ad will need to be reviewed and approved before it will be widely seen. And, if your new ads required a manual review the time-to-review could end up being measured in days - depending on the volume of new or edited ads being submitted.
So, long story short, condensing three ad groups into one new one along with the other changes you have mentioned might easily explain the lowered impressions. And lowered impressions could easily explain the lowered clicks.
