[1.0.1-HARD-MODE-TEST4] Copy and paste causes exceptions and lock up.

[dusk pike]

Sometimes when copying a part of my factory in Manufacture/Hard scenario I get exceptions in the log. The second time it happened I did a paste thinking it might stop the exceptions. Instead everything on screen disappeared including the GUI. I couldn't access the menu either. But it wasn't a PSOD as the background was still there and animating. I can't reproduce this. Just making a report just in case others run into this and can add to it.

Here are the distinct errors/exceptions found in the log:

1. Exception ("Stored island does not match"): A stored island Layout_RailLiftUp1X1X2 does not match the current island to remove, thrown in MapLayout.RemoveIsland and surfacing through ExtendedMapLayout.Clear, StagingPlacementMapExtender, and LazyEventMapLayout.RemoveIslandLazyStep.Execute.

2. Exception ("Trying to remove non existing island"): ExtendedMapLayout.RemoveIsland throws when attempting to remove island SpaceBelt_LeftTurn at GlobalChunkCoordinate(2681, -72, 1), called repeatedly via StagingPlacementMapExtender.ApplyChangesToMap and BunchEditScope.Dispose.

3. NullReferenceException: Object reference not set to an instance of an object in PlacementInputHolder.As[T], propagating through ModularEntityPlacer.GetPlacementState and ModularEntityPlacer.Update; also occurs in MousePlacementTracker.Track at GlobalChunkCoordinate(2693, -21, 0).

4. ArgumentException: A duplicate key IslandDescriptor(Layout_RailLiftUp1X1X2 @ (GlobalChunkCoordinate(2694, -51, 0);Rotate180)) was added to a Dictionary in LookupQueue.Enqueue, rethrown as an AggregateException.

Errors while cut/paste in Hex mode
Done • Priority: High • Fix: 4 - Early Access • Resolution: Done

The player experiences choppy and lagging behavior when using the Copy/Paste feature in Hexagonal mode. The issue occurs specifically after cutting Structures and copying a small Stacker factory. Error messages appear in the game log when performing these operations. The player has temporarily disabled the log as a workaround. This issue impacts the ability to smoothly use the copy and paste building functions in Hexagonal scenario.

Copieslist log error occurs when copying something
Done • Priority: High • Fix: 1.0 Release [1.0.0] • Resolution: Fix Verified

When copying a Space Platform or other structure in Classic Mode with the Regular scenario, a "CopiesList" log error is triggered. The issue is reproduced by placing a Space Platform and then copying it. The error indicates an inefficiency in the blueprint placement rather than a functional bug. The fix converted the log message into a warning for non-editor environments, and the fix has been verified.

NullReferenceException: Object reference not set to an instance of an object when copying a BP in build mode after copying a BP in space mode
Done • Priority: Critical • Fix: 1.0 Release [1.0.0] • Resolution: Fix Verified

A NullReferenceException occurs when copying a blueprint in Machine View after previously copying a Space Platform in Space View. The copied blueprint gets instantly deselected and a crash report is generated. The root cause appears to be related to multi-thread safety when querying connectors across different views. The issue is intermittent and was primarily reproducible once per build session after loading a save, making it difficult to consistently trigger. A partial fix for multi-threadi...

Play field disappears after Copy Signal Producers from Normal Scenario
Done • Priority: High • Fix: 4 - Early Access • Game: 0.0.0-alpha23 • Resolution: Done

Global Signal Transmitters share state between savegames in the same session. When a player inputs a shape into a Global Signal Transmitter in one game mode, then starts a new game in a different scenario without restarting, the Global Signal Receiver in the new game outputs the shape from the previous savegame. This causes the game to break when attempting to process shapes that should not exist in that scenario, potentially causing the play field to disappear and preventing the savegame fro...

Console Error when blueprinting fluid extraction platform
Done • Priority: Low • Fix: OLD Early Access • Resolution: Done

When copying a Fluid Asteroid with CTRL+C and hovering the Cursor with the Blueprint over the screen, a console error message spams at every coordinate the Cursor hovers over. The issue occurs after marking an existing Fluid Asteroid and copying it using Copy/Paste. The error appears while hovering the copied Blueprint before placement. Reproduction is inconsistent and the developer is gathering more information from the user. The issue has been fixed.

ctrl X does not work during autosave, deletes but does not copy
To Do • Priority: Low • Fix: None

Cut does not work during autosave, deletes but does not copy. When using Area Selection and pressing Ctrl+X while an autosave occurs simultaneously, the selected structures are deleted but not copied to the clipboard. The expected behavior is that the selection should be both deleted and copied for pasting elsewhere. The issue can be recovered using undo. The bug is difficult to reproduce but has occurred multiple times.

[1.0.1-HARD-MODE-TEST4] Copy and paste causes exceptions and lock up.

[hazy kiln]

Can I have the save file? Also the first thing the log file mentions is a rail lift. Do you have any of the ones from the DLC? Maybe that is causing it?

[dusk pike]

Same save as the slowdown bug. But the two times it happened I couldn’t reproduce after restarting the game. The DLC doesn’t work in the hard mode test versions.

✅ Thank you for providing further information, our team will have a look again!

[hazy kiln]

Have you had the problem since?

[dusk pike]

I ha en’t been doing major edits since finishing manufacture/hard.

I am going to close this for the time being. No one else has reported any issues with this.
Tell me to reopen this if you can figure out what triggered it?
