Build 25424449

This update provides a number of fixes to issues that have been reported, including

• Full save backwards compatibility - old saves will now be upgraded to new save format automatically

• You can now choose which features to import: roads and railways, buildings, land and water, and optional terrain. Import progress, cancellation, and retries are clearer. Fixed import options not appearing from the main menu.

• Significantly improved stability of import workflow. This should especially help with lower end hardware and RAM requirements.

• Improved hillside-building placement, roof selection, terrain and water display, and handling of memory limits when opening large maps.

• Windows now defaults to DirectX 12. You can switch to Vulkan in Video settings and restart to apply. For startup troubleshooting, use --vulkan or --dx12 in Steam Launch Options.

• Minor enhancements to develop workflow and traffic (more to come)

As always, thank you to everyone who has provided feedback or reported bugs.
