 When the client receives a [ReceivedItems](#ReceivedItems) packet, if the `index` argument does not match the next index that the client expects then it is expected that the client will re-sync items with the server. This can be accomplished by sending the server a [Sync](#Sync) packet and then a [LocationChecks](#LocationChecks) packet.
