[Freeciv-Dev] (PR#18257) get_invention() assert failed

assert (tech == A_FUTURE || (tech >= 0 && tech < 
game.control.num_tech_types),
     "../../freeciv-patch/common/tech.c", line=63)
failed.

Reproducible with revision 12042 + patch #18222 + attached autogame, but 
only in year 2004.
My guess is that it has something to do with initial science bonus when 
establishing trade routes.
