Which is why it's been recommended on here many times that you should create a second ad and only delete the old one after the new one has been reviewed and approved.
When you change an ad, it's put back into editorial review. When an ad is in editorial review, it's not shown on partner sites or in the content network.
To keep full exposure on all the available channels, keeping the old ad, which has passed editorial review running, allows your old ad to be shown until the ad passes editorial review and can be shown across the entire network.
Once you have another ad which can give you full exposure, then you can delete the ad you no longer want.
This is also why I suggest always keeping more than 1 ad in a group. If something suddenly happens (price change, landing page changes, etc), having an ad (even with a lower CTR) available if you MUST delete the better ad, at least keeps your exposure across all channels.

However, if you do continuously run 2 ads in a group in order to have one as a "backup", you have no choice except to have the "worse" ad showing at least occasionally. Unless there is a way that I don't know about to pause an individual ad within an ad group. All I see is "Delete" and it doesn't even provide the customary confirmation prompt.
