[295] problem after recapuring my only city.

Early in one compaign, I lost a unit from a very-nearby kingdom took my still-undefended capital.  There was no warning on the screen when this happened, which might be an issue but is not my main issue.

Took it back in a few turns an played along until it noticed that I hadn't had any new techs for a while.  Then the reseach screen turns until next discovery was some huge number that filled the whole field.  New game time.
