[Freeciv-Dev] unknown terrain type error (PR#974)

[Francois Taiani <francois.taiani@xxxxxxxx>]

Hi everyone,

I stumbled on a strange error message while trying to load a previously
saved game: 

unknown terrain type (map.t) in map at position (41,46): -111 ''

After that, the server aborts. Following is the whole server output.

server/civserver -f aztec.current.sav.gz 
This is the server for Freeciv version 1.12.1-devel

I'm using the cvs snapshot of September 11. I've uploaded the
corresponding savegame at
ftp://ftp.freeciv.org/freeciv/incoming/aztec.current.sav.gz. Has anyone
a clue of what may be going wrong ?
