[Freeciv-Dev] Re: decrement_pending_seen

[Jason Short <jshort@xxxxxxxxxxxxxx>]

This is a known problem; see PR#4757.

We need an easy way to reproduce it.  The problem is it's not usually 
reproducable from saved games, since the random number generator is 
changed when you load a saved game (PR#4773).  I have a 30-AI autogame 
that will trigger the assert in the year 1850AD :-(.
