New content and improvements
* Modular ramps can now go up to height 4, being able to go above train tracks.
* Vehicles now approach ramps slightly faster.
* Trade dock cargo is now included in the global search.
* Increased the number of switchbacks allowed in a single train path from 16 to 32.
* Trains no longer plan switchbacks inside critical sections.
* Vehicles that cannot cross water no longer report "struggling to navigate" because of bridges.
* Improved job assignment so that regular trucks stop hogging cargo reservations that only amphibious trucks can deliver.
* Pasted blueprint strings are now limited to 64 levels of nested folders.

Performance
* Virtualized the save and load window lists, removing the lag caused by having too many save files.
* Optimized the train track inspector; checking whether tracks can be electrified is now spread over several frames to avoid a hitch when opening it on very long track sections.

Fixes
* Fixed dump trucks failing to path to mega-excavators placed in narrow areas.
* Fixed trains recovered in depots failing to find a path because their speed was not reset.
* Fixed minor train teleportation when changing track length or critical sections near a switchback point as the train was approaching it.
* Fixed train track support previews not being cleared correctly, which caused errors and allowed impossible changes when using Ctrl+Shift+wheel.
* Fixed the train station waypoint tool freezing the game when the selected track was removed.
* Fixed vehicle connectivity sometimes reporting incorrect disconnects.
* Fixed rockets that could end up stranded at the map origin.
* Fixed rounding losses in unity from decorations, which is now aggregated across all settlements at once.
* Fixed chart highlighting stopping to work after the chart refreshed its data.
* Corrupted save files now fail with a clear error instead of an out-of-memory error.
