Bug: Case of the Dying Mages (and God)

[Fate]

I recently had this problem (twice in a row) in a LAN game. My friend and I both have Macs (Both Leopard, for that matter), no mods whatsoever, all played over LAN. I noticed one battle where my borderline SC died after the replay showed a flawless victory. My friend said he had noticed a similar thing a couple turns earlier (I hadn't been watching all the replays).

Now, I have patch 3.21b, but I am not 100% sure he does, so that may be part of the problem (but wouldn't it say something if the patch numbers didn't match?). I do have a number of mods on my machine, but none of them were in use.

I can give no explanation.
