[SPZ2-5768] [1.0.0-RC2] Incorrect shape preview after changing shape producer

[pearl quartz]

Copy-pasted a shape producer with the default shape code of {CuCuCuCu} and then changed it to {SwSwSwSw} - but the shape preview still shows the original shape. Strangely, copy-pasting the updated producer to the other three belts does show the correct preview, but the original producer that had the code entered continues to show the wrong shape preview

Item producer and fluid producer shape previews/predictions don't update when configured via side panel
To Do • Priority: High • Fix: 1.1 Release [1.1.0]

Signal Producer shape previews don't update when the machine is configured via the side panel. After placing a Signal Producer and changing its settings through the side panel, the shape previews still show the old configuration. The previews only display correctly after the machine is copy/pasted. This occurs because the extended map's equality check prevents reprocessing the building when its configuration changes, causing the preview and simulation configurations to diverge. Shape previews...

Shape prediction breaks on changing infinite producer
To Do • Priority: Low • Fix: None

Shape Previews stop working correctly when the player modifies an infinite Signal Producer that is connected to the system. The issue occurs in a simple setup where changing the infinite producer causes the prediction system to break. This prevents players from seeing accurate shape predictions, which are important for planning factory layouts. The expected behavior is that Shape Previews should continue to display correctly even when Signal Producer settings are changed during operation.

Shape preview (belts) is sometimes incorrect
Done • Priority: Low • Fix: 1.0 Release [1.0.0] • Resolution: Done

Shape previews on conveyor belts sometimes display incorrect shapes when the source signal changes. When using a Signal Producer to feed Belt Launchers, some belts fail to update their preview even after several minutes, while others update correctly. The previews can be manually refreshed by hovering over the Belt Launcher with another structure without placing it. The issue affects any Belt Launcher, not just those connected to The Vortex. This bug has been marked as obsolete due to predict...

Predictions show wrong output
Done • Priority: High • Fix: Dimension Update [0.1.0] • Game: 0.1.0-pre4-rc1 • Resolution: Done

Shape Previews show incorrect Output on Machine Platforms / Space Platforms larger than 1x1. The predictions display multiple different Shapes that would be produced, but this does not match the actual Output. The issue was caused by a coordinate lookup problem in platforms larger than 1x1. Shape Previews used to work correctly before, so this was a regression. The bug has been fixed and predictions now display correctly.

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...

Belt predictions are still incorrect when loading savegames
Done • Priority: High • Fix: 4 - Early Access • Game: 0.0.1 • Resolution: Done

Shape Previews on Conveyor Belts display incorrectly when loading Savegames. The issue specifically affects complex factories with high connectivity between Space Platforms, where the topological order calculator breaks down. In the reported case, no Shape Previews were coming from a Blue Square Space Platform. The bug was caused by Space Belt Merges not considering all output possibilities and issues with the topological order calculation for highly connected platform networks. Multiple fixe...

Quitting and restarting the save makes this problem go away, fwiw

[lost obsidian]

yeah that's because changing the shape inside the producer doesn't update the shape preview system, i.e. you need to force an update, like by doing a cut and paste or reloading the save for example

[pearl quartz]

yep

very tiny issue in the grand scheme of things - but I felt like I need to report at least one bug if I'm in the closed beta :p

which I suppose is a testament to how solid the RCs are ahead of 1.0 release
