(svn r14769) -Change: when loading games in "network" mode use the start date of the save game for the server and all clients when loading the NewGRFs instead of the current date. Prevents desyncs caused by action 7/9s skipping parts of the GRF based on the date or some other variables that can differ at NewGRF load time.
