Questions about Nevada and California

[Shanon]

Hi,
I play with this (nice) game "called" Railroad Giant" but it is well "Pionneer".
I had two troubleshooting with missions Nevada and California.
"Ressources Centers" give NOTHING.
Tracks and Station are sided, trains arrive in it with correct cars but .. nothing is produced.
For those missions the game don't ask "prospectors" for ressources centers.
Only passengers work between cities.
During "Nevada", I won easily Trade Wars in Fallon and Reno, opponent trains disappear and the congratulations message said : "City Pioch of Pioch swin in the Gold..." ???
I discover all the map but neither Ressourcers Centers produced. I put the tracks till Elko and... "win".
I begin California mission, and it appears the same : no production in ressources center (game).
For Nevada and California missions danger (hazardous) icons (trapper, gunslinger, ...) do not appear on the map.
A lot of damages occurs with trains (demolish tracks...) and then all train are quickly "entirely lost"...
Please...advice and help.
Thanks
