    I encountered a crash while creating/editing a scenario in Train Simulator Classic and I’d like to report it in case it’s a known issue or someone has advice.

    What I was doing:
    I was creating a custom scenario in the scenario editor. While placing or editing consists, the game suddenly froze and then crashed to desktop.

    Error message:


    Exception Code: 0xC0000005
    Exception Info: OUT OF MEMORY

    Fatal error in mode LOAD_SCENARIO during update within DISPATCHER.
    The system is unable to run this scenario on the current configuration,
    we suggest either lowering the graphical quality settings or attempting
    to run the game in the 64-bit version, if this fails to resolve the issue
    please contact our Customer Support Team at https://dovetailgames.freshdesk.com
    Additional info:

    • I was in the scenario editor, not running the scenario.

    • This happened during editing, not on loading the route from the main menu.

    • The crash happened suddenly; there was no long freeze before it.

    • I am already using the 64-bit version of the game.

    • The route and rolling stock are modded, but everything loads normally until this point.
    System info (if needed):

    • OS: Windows 10 64-bit

    • Game version: Train Simulator Classic (64-bit)
    Has anyone else encountered this specific error while editing scenarios?
    Is this a known memory leak, dispatcher bug, or limit related to the number of consists / AI services / scenery objects?

    Any advice or confirmation would be appreciated. Thank you!
