I just loaded a savegame (DA beta 2A) to discover that all of the ship designs I had created during my last session had not been saved. All of my starports were still building ships that no longer had designs in the shipyard. This is the first time I have seen this happen.

Naturally, loading a new game destroyed my err.log from the previous session. I was playing as the Terrans, medium galaxy, if that is any help.
