See title.

Basically, pipes and belts at this scale register the other thing's previews.

Space Belt predictions will travel down Space pipes and vice versa
To Do • Priority: High • Fix: 1.1 Release [1.1.0]

Shape Previews incorrectly transfer between Space Belts and Space Pipes when they are connected. Shape Previews on a Space Belt can travel down a Space Pipe, and vice versa. The expected behavior is that shape Shape Previews should only travel down Space Belts, and fluid Shape Previews should only travel down Space Pipes. This can be reproduced in Classic Mode on a Regular scenario with cheats enabled.

The new liquid predictions treat conveyor belts like they are pipes
To Do • Priority: Low • Fix: None

When a fluid Signal Producer is connected to a Conveyor Belt, the Shape Previews system incorrectly displays paint predictions at the end of the belt, treating it like a Pipe. This occurs in Classic Mode when using cheats to place incompatible connections between fluid producers and belts. The issue is an edge case that only happens with intentionally mismatched connector types. Conveyor Belts should only display Shape previews, not fluid or paint predictions. The bug has minimal impact since...

pipe / belt prediction bug
To Do • Priority: Low • Fix: 1.0 Release [1.0.0]

The Belt Catcher / Belt Receiver incorrectly shows a shape preview expecting fluid from a Space Pipe / Platform Pipe. This is a display bug in the prediction system where the machine preview does not match the actual input type - belts should handle shapes while pipes handle fluids. The issue causes visual confusion as the preview suggests the Belt Catcher will receive fluid when it can only process shapes. This appears to be a straightforward fix according to QA notes.

Shapes can go through space pipes and vice versa
Done • Priority: High • Fix: 4 - Early Access • Resolution: Done

Shapes can incorrectly travel through Space Pipes, and fluids can travel through Space Belts. This occurs when Space Pipes are placed in the middle of Space Belts, causing them to act as connectors that transport Shapes. Additionally, Space Pipes can output onto Conveyor Belts, and Space Belts can transport fluid blocks from Conveyor Belts. Attempting to put Shapes into Pipes breaks the game. The expected behavior is that Space Pipes should only transport fluids and Space Belts should only tr...

The direction in which a pipe is built affects shape prediction in painters
Done • Priority: High • Fix: 1.0 Release [1.0.0] • Game: 0.1.0-pre6-rc1 • Resolution: Done

The direction in which a Pipe is built affects Shape Previews in Painters. When Pipes are built in the normal flow direction towards a Painter, the Shape Preview appears on the Conveyor Belt below. However, if the Pipe is built in the opposite direction, the Painter shows no Shape Preview. This issue was tested in version 1.0.0-alpha1 and was later marked as obsolete due to prediction refactoring. A savegame and blueprint were provided for reproduction.

Fluid overview prediction works backwards through space pipe
Done • Priority: High • Fix: 1.0 Release [1.0.0] • Game: 0.0.9-RC7 • Resolution: Fix Verified

When two Space Pipes join together and one of them splits elsewhere, the Fluid overview incorrectly predicts that fluid from the join point will arrive at the other end of the split. The Shape Previews show liquid reaching locations where it will never actually arrive. This occurs in Classic Mode when Space Pipes connect and split in certain configurations. The expected behavior is that Shape Previews should only display predictions for locations where fluid will actually reach. This issue ha...
