// donecount

// If we send updates too fast and world has not had a chance to confirm and then inform clients to set their
// absolute state we will miss and discard updates because each update sets the same donecount
//
// Example: say we have a 100 kill task and we kill 10 mobs in an AOE, world gets 10 updates at once but they are
// all from the same donecount so world only confirms 1 was actually killed and the task updates only 1 which is not
// intended behavior.
//
// In this case we need to ensure that clients at the zone level increment internally even if they aren't
// necessarily confirmed by world yet because any of them could inform world of the next donecount so we need to sync
// zone-level before sending updates to world
