I have had some odd mega event behavior in my last game.

While playing on a Small map, Normal AI, Custom Civ usuing the Yor Techtree Against the Humans and Altarian, I got the Disease Mega Event.

The Event WND stated I needed to research Xeno Medicine to find a cure.
From experience I knew I needed to get Disease Cure after that.

There is no Xeno Medicine in the Tree. I had to trade for it. Further more, There is no "Disease Cure" available for me to research even after I have Xeno medicine. In addition, it deleted one of my ship designs right out of the Shipyard and changed all planets producing that ship to "Nothing"

For those who beta'd. I'm assuming you research either Antivirus or Firewall, but they've been there since the start of the game. Is that correct?

Fortunately/or not, despite my now apathy stricken citizens and their total lack of productivity (I didn't realize everythign in teh civ went to 0, even my logistics!), I had enough momentum to capture a few strategic planets and CF the humans, wining, so I never got to finish researching Antivirus and Firewall (1175 turns my rear end!)

I'm a little more concerned about the disappearing ship in the ship yard. I'd be glad to zip up everythign you need (Debug.err, the Savegame), but I don't see an "attach" button here in the forum.... Grrrr.
