What version are you playing? If my memory serves the capaign isnt all that stable in many of these versions... if ever.. I tried it once long ago had a weird random bug glitch out some diplo quest. Been playing the stand alone large rediculous maps ever since through all the beta versions being worked on to make EWoM more stable & fun.

hum... ok... which one is that?

When I got EWoM i was using 1.09e that official digital D/L version... since then I switched to the beta's & were up to 1.09v (well we were when I fell asleep this morning after my last marathon session)

From everything I've read I think it would be safe to say that for the moment you should take any crashes or game ending glitches with a grain of salt if you want to play the campaign. At least untill the hard working devs at StarDock finish nailing down the stability issues ,& other issues, and they have time to make the campaigns' work as intended.

Well good luck and good hunting, going to go check out the latest beta that I spent 6 hours dreaming about.
