Scenario blues

[Cherokee158]

I am working on a scenario which is beset by bugs. This is hardly suprising, as it is my first attempt at the arcane art of scenario creation, but I seemed to have hit an impasse. Only one of my civilizations will launch...if I attempt to play as any other Civ, the game crashes to the desktop. Any ideas of what could be going wrong?

Yes, make sure that *no* units that are active (or can be
produced) have 0 hit points. I downloaded a couple of scenarios
with that bug, and saw the same symptoms as you seem to be.

Another possible problem is that a tech is being research that
has a prerequisite tech whose prerequsite is "NO".
