#[1.0.3-RC3] Windows 10 - Wagon unloading not producing correct (or omitting) shape previews

The indicated shape preview is alternating between cyan and red trader shapes when it should only show cyan. Both shapes are unloaded from the first wagon on a similar configuration (shape/spacer/shape/spacer/shape), but differently routed trains. Also no shape previews are shown from the third and fifth wagons on the train. Pipes and machines at both ends of the line have been cleared and deconstructed/reconstructed from scratch, yet reproduces this behavior.

Train predictions are ending up where they shouldn't when another train is using spacers
To Do • Priority: High • Fix: 1.1.0 Release • Game: 1.0.0-beta2

Shape Previews for a train are appearing in incorrect positions when another train on the same route uses Spacer Wagons. In the reported case, a train with one Shape Wagon shows three Shape Previews instead of the expected one, because the Spacer Wagons on a different train are incorrectly influencing where previews are placed. To reproduce, start a new Classic Mode savegame in the Regular scenario, enable cheats, and place the provided blueprint. Spacer Wagons on one train should not affect ...

Filler wagons block train predictions from shape/liquid wagons attached afterwards
To Do • Priority: High • Fix: 1.1 Release [1.1.0]

Spacer Wagons in a train consist block Shape Previews from appearing on Shape Wagon Unloaders and Fluid Wagon Unloaders that are positioned after the Spacer Wagon in the station. The issue can be reproduced by placing a train setup where a Spacer Wagon precedes Shape or Fluid Wagons. Shape Previews should correctly propagate to all wagon unloaders regardless of Spacer Wagon placement in the train. The bug persists as of the latest beta.

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.

Prediction for trains that have more wagons than the amount of loaders will be showing for the wrong unloader
Done • Priority: Highest • Fix: 1.0 Bugfixes before Feature Freeze • Resolution: Done

When a Train has more Wagons than Shape Wagon Loaders at a Train Station, the Shape Previews display on the wrong Shape Wagon Unloader. The previews appear on the first unloader instead of the last one that will actually receive the shapes. This occurs in Classic Mode when setting up a station where the number of wagons exceeds the number of loaders. The previews should indicate which unloader will receive shapes based on the train configuration and loading pattern.

Predictions don't show if a train has less wagons than the amount of unloaders
Done • Priority: High • Fix: 1.0 Bugfixes before Feature Freeze • Resolution: Done

When a train has fewer wagons than the number of shape wagon unloaders at a station, shape previews stop displaying on the unloaders. This occurs when rail tracks are modified to add extra unloaders beyond the train's wagon count. The expected behavior is that previews should still show for unloaders that can actually receive shapes from the available wagons. The issue was reproduced in Classic Mode by placing a train station, then replacing a rail segment with an additional unloader. This pr...

Train with a shape wagon and liquid wagon will only show predictions for the opposite order of unloaders
Done • Priority: Highest • Fix: 1.0 Bugfixes before Feature Freeze • Resolution: Fix Verified

When a Train has both a Shape Wagon and Fluid Wagon, the Shape Previews only display when the unloaders are in the opposite order compared to the Wagons. If the Wagons are ordered correctly to match the unloaders, no Shape Previews appear. The expected behavior is that Shape Previews should only show when Wagons and unloaders are in the same order. This occurs in Classic Mode and can be reproduced by placing a Train with both wagon types and observing the preview behavior.
