Please verify suspicion.
 

In the latest turn of one of my games a neighbour suddenly attacked me. There was no message from him and we had a treaty the previous turn. I had a few ships and none of them fired back despite the fact I was the only one on the end of a wormhole and went first. I suspect he broke the treaty, but then saved the turn and loaded it later to finish it thus the game saw he no longer had a treaty with me but since I received no message my ships still thought we were friends and so didn't fire. I think this happened to me before but I can't rememeber if my suspicions were correct. Can anyone tell me if this is probably what happened?

Megaevil empire? Maybe there was no message for whatever reason.

I had something simmilar happen to me once in stock, when I was just playing the computer. For some reason the game had started with 2 races using the same shipset and, I'm guessing here, the computer confused one, with which I had a millitary alliance with, with the other who I hadn't met. So my "friends" ships suddenly attacked mine.

Does his status on the empires screen show him at war or still with a treaty? If he is at war, you have your answer, but if he is still shown as having a treaty you may have a serious game bug.

If he broke the treaty, the status would be "None"

MEE only applies to AI, not human players.

Wait. Is is possible to send a message without any text, and thus it be invisible?

Breaking a treaty sends no message. But declaring war will. IIRC

Something sort of like this happened in CB#2. My empire had decided that peace is boring, and OH! look at all the shiny, resource-filled worlds! (this is a Disposable Society race, so everything is basically one-shot use; plus, insane amounts of construction capacity, no repair).

Anyway, I canceled the treaty with SJ, and was expecting on the next turn to lose quite a bit of hardware around our "joint defense" points. I had two ships and a big stack of satellites, he had a few carriers, 8 or so ships, and a bigger stack of satellites. Somehow, when the turn was processed, none of his ships anywhere fired a shot. I had two ships that magically jumped to Legendary status, as they took out all of those defenses, without a scratch.

Strange thing is, once SJ processed the turn again, with (I'm fairly certain) the same *.plr files, his ships started firing again. So, it's probably just some strange quirk in how turns are processed. Try running it again, and see if that fixes it.

There shouldn't be duplicate sets as the shipsets are built into the mod. It wouldn't be MEE as I suspect he is 1st. rewinding the turn showed he had a trade treaty with me, then he didn't. I don't think it's worth redoing the turn as the few ships I had wouldn't have stood a chance and now I know what he is going to do.

I think your theory might be right. He probably broke the treaty and the message was lost by the "save and re-load" bug that we've seen before.
