I've tried loading a couple of old games on
<ftp://ftp.freeciv.org/pub/freeciv/contrib/development/saved_game>

this:

This is the server for Freeciv version 1.12.1-devel
You can learn a lot about Freeciv at http://www.freeciv.org/

2: Loading rulesets
0: Invalid map line for y=0.  This may be a bug in FreeCiv; see
http://www.freeciv.org/ if you think so.
