Greetings everyone! Save files attached. I've been painstakingly playing the very punishing 1850 WA map and am almost 100 years into it with 280 trains. I micro every single arrival/departure, so you can imagine how much time has been poured into this save. For whatever reason, just as train 241 comes in (about 5 seconds in) the game hangs and exits to the OS. It also seems to hang if I grab the scrollbar and drag down rapidly through the train list. No error is given, just a brief hang followed by a crash / exit to OS. I've tried saving a different version after making some in-game tweaks (deleting trains, adding trains, other minor changes) and have tried virtual OS and host OS restarts. I've tried changing resolution and other interface settings as well. Nothing seems to work so far. I've loaded an older version of the save (2 game years, an eternity for me) and ran it past the 'expiry date' of the troublesome save, and all seems ok. My next step will be to reinstall the game and copy these over, but I'm hesitant to do that cause of all the completed scenarios. Any help any of you can give me here would be greatly appreciated! Two files attached: Version 12 is the one that has the issues, Version 11 is the previous functional save AAustralia WA1850 - (12).GM2 Australia WA1850 - (11).GM2
