Riposte solution
The conditional STORE/UID EXPUNGE failed because the message was modified by someone else. In practice, if you tried to change a message with a condition (like "only if unchanged"), that condition wasn't met. To handle this, refresh the message state (fetch the latest flags or data via Riposte), then decide if you want to apply your changes again. Essentially, another client updated the message, so your expected state was out of date.
