Patch 3.0.16

Performance

• Fixed multi-second freezes on big automation maps and when closing the build menu on large saves
• Train labels and panels no longer rebuild the UI every frame
• Smoother spawn/despawn bursts, distant train sounds culled, slow frames no longer snowball into stutter

Maintenance and service locos

• Service loco can now couple a train broken down at the mouth of a Coach Yard (loading an affected save unsticks it)
• Service loco with nothing to couple at a Coach Yard turns around instead of parking there for good
• Service route Reverse step now reverses where placed
• Service loco re-entering from a border at the same platform no longer collides with itself (was a game over)
• Route editor no longer reports "missing signal" for valid signals near tunnel-crossed platforms
• Resuming a pushed broken-down train no longer teleports it behind the coupled service loco
• "Stopped by player" badge clears immediately on Start for a dwelling repaired train

Fixes

• Map editor: Edit Map no longer crashes after a session where a contract was rejected
• Happy Passengers: demand no longer turns unhappy one departure early
• Audio: tunnel and auto block pass rumble now follows Master and Ambient sliders and mutes in the background
• UI: Waypoint and Auto-block build buttons now have distinct icons
• Fixed a board switch refresh error when rebuilding a switch with one side unconnected
