[SPZ2-5304] [1.0.3-rc3] Belt finished shape icon flickering all possible shapes from a rail network

[versed shoal]

The rail network has two trains of different colors holding different shapes, however with route configurations the output shape flickers between all possible shapes even though only one is possible. This flickering gets compounded with cutting, rotating stacking, filtering through all possible combinations if different shapes where used.

New predictions start rapidly flashing if shapes are returned to the original loader from the unloader and there is a conflicting shape being added
To Do • Priority: Low • Fix: None

Shape Previews start rapidly flashing when shapes are looped from a Shape Wagon Loader through a Shape Wagon Unloader and back to the original loader while a conflicting shape is being added. This occurs in very tight loops where shapes are returned and pinned, causing the predictions to flicker instead of remaining solid. The issue is reproduced in Classic Mode by creating a loader-unloader loop and introducing a different shape type back into the loader. The expected behavior is for Shape P...

Train predictions are accounting for all loaders when the shapes will never get to the unloader they are indicated on
Done • Priority: High • Fix: None • Resolution: Missing Feature

Train Shape Previews show all loaded Shapes on every unloader even when those Shapes will never reach certain unloaders due to earlier drop-offs. This occurs when a Train picks up Shapes, drops them off, picks up different Shapes, and drops those off - all unloaders display predictions for all loaded Shapes regardless of the actual route. The user expected predictions to accurately reflect which Shapes would reach which unloaders, but this was closed as working as intended since precise predi...

Train predictions aren't displayed if a loader is going to receive different shape packages
Done • Priority: Lowest • Fix: None • Resolution: Won't Fix

Train Shape Previews are not displayed when a Shape Wagon Loader receives different Shape Packages alternating on the same Conveyor Belt lane. The user expected the Output predictions to show both package types alternating, similar to how a Shape Wagon Unloader displays multiple shapes or how a Wagon Transfer shows predictions. However, this is by design - the game cannot predict ratios when multiple items feed into a single Loader lane, so predictions are nullified to avoid confusion.

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 preview (belts) is sometimes incorrect
Done • Priority: Low • Fix: 1.0.0 Release • Resolution: Done

Shape Previews on Conveyor Belts sometimes fail to update when the shape being transported changes. After reconfiguring a producer from one shape to another, some belts continued displaying the old shape preview indefinitely, even after extended wait times. The issue appears related to Belt Launchers not triggering a preview refresh, and it is reproducible with any Belt Launcher, not just those delivering to The Vortex. Hovering over the affected Belt Launcher tile with another machine forces...

space belt predictions are wrong if other shapes merge "later"
Done • Priority: High • Fix: 1.0.0 Release • Resolution: Done

Space Belts show wrong Shape Previews when other shapes are merged further down the line via a Merge. The incorrect predictions appear on the Space Belt before the merge point, seemingly influenced by shapes joining later in the path. This was resolved after a prediction refactoring, making the issue obsolete.
