It's preventing you from clobbering a later revision that was added. This can happen if you have the following situation:
* Show user rev1 of document in UI * Couchabse lite sync's rev2 of doc in background * You try to save user's changes, based off rev1 (which is now stale) * Couchbase Lite throws that error, since you passed in rev1 as the previous revision, but rev1 is no longer the latest revision it knows about. Does that sound like what's happening in your case? If you debug it, you should see that you are trying to save a revision based on a stale previous revision. If not, it might be a bug in Couchbase Lite worth looking into.
