i thought about this for a bit, turns out, messages need UIDs (Unique IDs) as much as players need them. Because if they don't have them, then there's not difference between twBecause if they don't have them, then there's not difference between two same messages. Of course, you can only send it once, but there's no guarantee that it will be recieved. Instead, you need to continue sending the message PLUS the UID, and only add it to the "server" list if it is unique. Every unique message has a unique UID.
