[SPZ2-6308] [1.0.3-RC3] Route Configurator may cause shape previews to break if too close to a train

[pastel wyvern]

If we use a route configurator too close to a train start, it may cause the shape preview to break. I provided recordings of both a minimal setup and during my playthrough

For now the workaround is to place the depot one behind (so the head is not on the intersection).

NullReferenceException: Object reference not set to an instance of an object: Occurs when traying to place a train spawner over the rails of another train depot
Done • Priority: Highest • Fix: 1.0.0 Release • Resolution: Fix Verified

A NullReferenceException occurs when hovering a Locomotive Depot over the rails of another Locomotive Depot, causing the screen to turn purple and the game to become unresponsive, forcing the player to return to desktop. The issue can be reproduced by placing a blueprint with multiple trains and attempting to position a Locomotive Depot over the starting rails of another, sometimes requiring rotation. The expected behavior is that the game should not become unresponsive during placement. The ...

"ArgumentException: handle" exception appears when placing a train basic BP with shape preview on anywhere
Done • Priority: Critical • Fix: 1.0.0 Release • Resolution: Fix Verified

An "ArgumentException: handle" exception occurs when placing a blueprint containing a Locomotive Depot and loader while Shape Previews are enabled. The error originates in the train prediction registry when clearing read access. This causes the screen to turn purple and an exception to appear on screen. The issue does not occur when Shape Previews are turned off. The fix has been verified.

NullReferenceException when trying to place a rail over a train spawner
Done • Priority: High • Fix: Dimension Update [0.1.0] • Game: 0.1.0-pre2-rc1 • Resolution: Done

A NullReferenceException occurs when attempting to place a Rail over a Locomotive Depot. The error triggers when placing track from the back of the depot through to the front, causing the screen to go black and displaying error messages. The issue can be reproduced in any Game Mode by enabling cheats, placing a Locomotive Depot of any color, and then attempting to route a Rail through it from back to front. The error originates in the RailDefinitionPlacementSolver when processing Space Platfo...

Train predictions aren't recalculated after rerouting a train
Done • Priority: High • Fix: 1.0.0 Release • Resolution: Fix Verified

Shape Previews are not recalculated after rerouting a train. To reproduce, start a new Classic Mode savegame in the Regular scenario, enable cheats, place trains, and reroute a train to go in a new direction. After rerouting, Shape Previews for the new direction are not updated. Expected behavior is that Shape Previews should automatically refresh when a train's route changes. This issue has been fixed and verified.

Shape prediction does not update at vortex when changing rail route configuration from the same unloader into another
Done • Priority: Highest • Fix: 1.0.0 Release • Resolution: Duplicate

Shape Previews at The Vortex do not update correctly when the player changes a Train Route configuration to redirect a train from one Shape Wagon Unloader to another. When two differently colored Train Routes deliver shapes through the same Shape Wagon Unloader, both Shape Previews display correctly on the Conveyor Belts. However, after rerouting one train to a different Shape Wagon Unloader, the Shape Previews on The Vortex fail to reflect the change. The expected behavior is that Shape Prev...

Shape Predictions do not work consistently in large savegame
Done • Priority: High • Fix: 4 - Early Access • Game: 0.0.0-alpha23 • Resolution: Done

Shape Previews do not work consistently in large Savegames. When loading an affected Savegame and navigating to various Space Platforms, attempting to create Splits on Conveyor Belts often fails to display Shape Previews. In some cases, predictions appear only after repeatedly replacing or connecting Conveyor Belts. The issue is particularly noticeable in highly connected factories with many Structures. Expected behavior is that Shape Previews should consistently appear when drawing Split Con...
