Update - we implemented a "diff" algorithm, and only post operations to mutate() if we absolutely have to. This bypasses the problem. Therefore this issue is not of critical importance to us anymore.
For more details... To recap the problem - if you REMOVE a target and then ADD it again shortly afterwards, the ADD is ignored and never appears in the campaign. The solution is to implement a "diff" algorithm so the mutate() operations only reflect true changes. In other words, don't remove a Language=US if you are just going to add it back again. My first implementation of this tried to rely on the underlying Criterion objects themselves, hoping that their equals() and hashCode() implementations would find matches for me. Unfortunately this wasn't the case, because those objects are usually not fully defined. For example there are many fields which the documentation says are "read only" and ignored for ADD operations. Therefore we don't bother setting those when we create our desired list. Also, when we request the data from Google, we don't necessarily select every single field, so some objects might be missing some data. Instead, I made a little adapter which builds a "key" that uniquely identifies the criterion, only paying attention to the fields that matter to our application. Then we perform our diff using those keys. After that I discovered that a lot of the objects were missing important fields, so we had to add some more fields to our Selector. In the end this fixes it. The moral is - only mutate() stuff that you truly want to change.
