[SPZ2-6033] [1.0.0-beta4] Game freezes randomly

[fading nest]

Sometimes, when trying to place something train-related, although not always after actually clicking to place it, my game simply freezes. This has happened to me over 10 times in the past few days and I have not been able to pinpoint the exact cause. I have tried playing with all the available launch (graphics) options and with multi-threading off, still getting the issue. In the attached save (my full main save), I have experienced this issue multiple times, even from the current state. I'm playing on a windows 11 laptop with nvidia geforce rtx 3060.

Train related platform placement is causing the following error ArgumentException: An item with the same key has already been added
Done • Priority: Critical • Fix: 1.0 Bugfixes before Feature Freeze • Game: 1.0.0-dev • Resolution: Done

Train / Rail related Space Platform / Island / Platform placement causes an ArgumentException error with duplicate GlobalChunkCoordinate keys, resulting in an unrecoverable purple screen crash. The issue is triggered reliably when placing Shape Wagon Loader / Train Shape Loader / Shape Wagon Unloader / Train Shape Unloader / Fluid Wagon Loader / Train Fluid Loader / Fluid Wagon Unloader / Train Fluid Unloader (un)loaders over Rails / Train Tracks / Railway in the opposite direction, or when R...

Laptop experiences a game crash on certification tutorial.
QA • Priority: High • Fix: None • Game: 1.0.0-alpha5-rc2

shapez 2 crashes randomly during the Certification phase, freezing and displaying a crash error window before becoming unresponsive. Log analysis reveals two errors: a savegame failing to load due to a version below the minimum supported, and an exception in achievement logic when leveling up a research upgrade. The crashes may be related to the user running DirectX 12, as switching to DirectX 11 was suggested as a workaround. The expected behavior is that the game runs without crashing durin...

NullReferenceException when trying to place a rail over a train spawner
Done • Priority: High • Fix: Dimension Update [0.1.0] • Game: 0.1.0-pre2-rc1 • Resolution: Done

A NullReferenceException occurs when attempting to place a Rail over a Locomotive Depot. The error triggers when placing track from the back of the depot through to the front, causing the screen to go black and displaying error messages. The issue can be reproduced in any Game Mode by enabling cheats, placing a Locomotive Depot of any color, and then attempting to route a Rail through it from back to front. The error originates in the RailDefinitionPlacementSolver when processing Space Platfo...

Black screen and error messages when tring to build line over the train launcher
Done • Priority: Highest • Fix: Dimension Update [0.1.0] • Resolution: Done

When building a Rail over the first Train Launcher placed, the screen goes black and an error message is spammed. The error states "Trying to add two valid intersecting entities" at a specific coordinate. This occurs when placing a Rail that crosses over itself to create a Train Launcher and then continuing to build over it. The issue has been fixed in the latest version and no longer occurs when building over Train Launchers.

Crash reported by user after new update
Done • Priority: Medium • Fix: None • Resolution: Cannot Reproduce

A player experiences repeated game crashes after updating to version 0.1.0. The crashes occur within minutes of starting a new Normal difficulty save, typically after completing one or two milestones. Log analysis reveals a SerializationJsonException when reading a blueprint file and NullReferenceException errors during deserialization. The issue appears to be caused by incompatibility between save files from version 0.0.8 and 0.1.0. The problem was resolved when the player deleted the old sa...

Done • Priority: Medium • Fix: Dimension Update [0.1.0] • Game: 0.0.9-rc6 • Resolution: Cannot Reproduce

The game / shapez 2 freezes and crashes when configuring Machines / Buildings or interacting with text input fields on Windows 10 Steam. The crash occurs when trying to change text on a Display / Shape Display / Signal Display, configure Wire / Logic Wire / Signal Wire Machines / Buildings, or create and name Blueprints / Saved Layouts / Templates. The issue persists even after disabling multithreaded saving and parallel rendering settings. The crash logs show symbol resolution failures in Un...

I suppose this will probably just be an issue with my performance/RAM, but I don't think that should be happening with 200k machines?

[robust lake]

The game freezing when only doing train related actions shouldn't be happening.
But knowing your system specs might help. What are your system specs other than the nvidia geforce rtx 3060?

[robust lake]

I triggered it somehow 🙂

🎫 Many thanks for reporting this issue! We have created an internal ticket for further investigation and will keep you updated. The internal ticket ID is SPZ2-6033 for reference. If you want to provide further information, just comment on this thread.

[SPZ2-6033] [1.0.0-beta4] Game freezes randomly

[robust lake]

Might be something to do with train shape previews.
I didn't have any issues if I turned off the shape previews which you can do in the General settings tab at the bottom.

[fading nest]

I have tried turning those off yesterday and haven't encountered it (yet)

I'll send the specs once I get home (~4h)

[fading nest]

So I have: 11th gen intel i7 2.3GHz, 16GB ram and the gpu mentioned above

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

Luckily it's happening to me as well, so its not your system.

I was able to create a few steps that triggers the bug about 8 out of 10 times for the internal bug report.
It seems to do it randomly at other times as well. I hope that is all part of the same thing.

I just had the same issue on beta6. I'll attach my log and save file in case it helps. Seems to have frozen up Steam somehow too - I could only close the game by sending a SIGKILL with the process.
I'm on Linux (Debian 13) with the following specs, in case it helps:

• CPU: AMD Ryzen 7 7800X3D, 8 cores
• RAM: 32 GB
• GPU: AMD Radeon RX 6950 XT
  I also crashed when placing a quick train stop, so that would further suggest it's train-related

Here's my log:

Unfortunately upon booting up the save again and placing the station, the bug didn't reappear, so I reckon it'll be one of those really hard to debug issues lol
