This happened to me too... I think all games got rolled back a few hours or something. I don't know of any notice given to us, at least not in an obvious place to look. Anyway, in one of my games I changed up orders and the next morning I checked that game and the orders were back to what I had before the change... I know there were other problems, so I just assumed it was part of that whole deal, but I remember thinking to myself that some people could get burnt by it since many people update orders and then don't check back for a while since it's easy to get busy with other things...

Can any mods expand on what happened?

Kestas had to rollback to an earlier database but it wasn't much earlier. This was because apparently we've surpassed 2^31-1 orders which is the maximum phpDip currently supports. As a result, some wonky bugs were arising, mostly because orders were for units that didn't exist.

There were notices I think. I'm sorry for those affected but it shouldn't happen again as Kestas has made sure there is an automatic reset and a mechanism that checks if units and orders match up.

At least this was my understanding.

Yes, it may have not been much earlier, but as I was out without internet from saturday morning (rolling back during around 1 hour, exactly the time I had to check here) until yesterday night, I could'nt change to what proper moves I had (I use to finalize when I have to go out, just in case I can't come back soon enough)
