[PvK]

This happened to me once. I thought my browser had messed up the first time, so I "re-sent" it, but it actually had got it, so it took my re-send as if it were my orders for the next turn, too, which caused the AI to take over a lot of things.

One amusing thing it decided to do was to retrofit my newly-completed colony ship to a specialized Version that was the same but had very few engines!
