[SPZ2-6250] [1.0.0-A5-RC2] Trains sometimes vibrate when stopped | Shapez 2 | Page 1

when stopped under certain conditions, trains will visually "vibrate" in place. i can't pin down exactly what conditions need to be met, but it typically seems like trains need to be turning or going under the end of a rail.

Trains are not updated in sync with simulation / camera
To Do • Priority: Medium • Fix: Probably Never

Trains are not updated in sync with simulation or camera movement. When holding down a camera movement key in Space View to pan the camera, Trains visibly fall back or jump ahead when frame time differences occur. This desynchronization happens both with and without parallel rendering enabled. The issue appears to be related to trains being updated at the end of the update cycle, causing them to become out of sync with camera position updates during continuous camera movement.

Trains spinning when returning to base
Done • Priority: High • Fix: Dimension Update Patch 1 [0.1.1] • Resolution: Done

Trains keep spinning when returning to the Locomotive Depot after cutting a Train Launcher and rebuilding it over level 2. The issue occurs when creating a train with 3 wagons on level 1, raising a 3-tile rail section to level 2, attaching a ramp for minimal jump height, then cutting from the elevated rail to the ramp end, leaving two spaces, and filling those spaces with rails. The expected behavior is that trains should return normally to the depot without spinning continuously.

Trains may overlap as they leap
Done • Priority: Medium • Fix: Future • Resolution: Won't Fix

Trains may visually overlap with each other when they leap between Space Platforms. This is a minor visual issue that does not affect gameplay functionality. The bug occurs during train transitions across platform boundaries. The development team has decided not to fix this issue as it would require too much effort for a cosmetic problem.

Train locomotives visual collision with wagons stopping at Train Stops
Done • Priority: Medium • Fix: 4 - Early Access • Resolution: Done

Train locomotives visually collide with wagons when stopping at Train Stops. When a train behind stops for a train ahead at a station, the locomotive appears to merge into or overlap with the wagon in front of it. This is a visual glitch where the locomotive sprite does not maintain proper spacing from the wagon. The issue occurs when multiple trains with wagons are placed along with several Train Stops. While trains function correctly, the visual representation shows incorrect positioning du...

Train wagons are misaligned when returning on a Rail Twister segment in gameplay.
To Do • Priority: High • Fix: 1.0 Release [1.0.0]

Wagons on a train become misaligned with the rail when returning through a Rail Twister segment. To reproduce, enable Supporter Edition features, start a Classic Mode game, build a Locomotive Depot with five or more wagons, and connect it to three or more Rail Twisters. As the train returns to the Locomotive Depot, the wagons visibly drift out of alignment with the rail. Expected behavior is that wagons remain properly aligned with the rail throughout the Rail Twister segment.

Trains do not slow down to other trains or blockers
Done • Priority: High • Fix: 0.1 - Feature Complete • Game: 0.0.9 • Resolution: Won't Fix

Trains do not slow down when approaching other Trains or blockers. This feature was intentionally omitted during a refactoring for simplification. When a Train encounters another Train ahead or a blocker Space Platform that prevents it from flipping upside down, it stops but visually clips through the obstruction instead of gradually decelerating. The issue is considered an edge case and marked as Won't Fix unless it causes problems elsewhere.

still working to reliably reproduce this - any help/info is appreciated

#

What space grid / coordinate does this happen? I don't know if that matters.

#

I think they added a "wobble" around corners with a recent release. I'm guessing this is a result of that.

vocal dawn Mar 13, 2026, 5:55 AM

#

oh maybe

#

i'm looking now and it's happening at 0|A

#

so the middle of the map

green violet Mar 13, 2026, 5:56 AM

#

So it's probably a non-damped wobble effect.

vocal dawn Mar 13, 2026, 5:57 AM

#

what's weird is it's much more subtle in slow motion

#

same speed, but way less intense

@vocal dawn Did you find a reliable reproduction for this issue? I did see it on Alpha 5, but I have not had success in internal builds. There was some changes around this area, but I want to be sure we have the steps right before I call it fixed in a future build.

vocal dawn Mar 13, 2026, 8:41 PM

#

i could get it to consistently happen when trains were stopped/colliding around turns

robust surgeBOT Mar 13, 2026, 8:41 PM

#

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

vocal dawn Mar 13, 2026, 8:42 PM

#

i believe it may have sometimes happened when going below the rail, but i'm not sure on that

manic adder Mar 13, 2026, 8:45 PM

#

Alright, I had a lot of windy tracks attempting to reproduce it, so I think we can call this one fixed in the next update. Thank you for the quick response!

robust surgeBOT Mar 13, 2026, 8:54 PM

#

✅ This bug has been already fixed on internal builds and should be fixed with the next release. Should this bug not be fixed with the next build, as the reporter, you can use /reopen-bug to reopen it again. Alternatively you can report a new issue.

I can still see this happening in 1.0.1-HARD-MODE-TEST3. weirdly, it seems to only happen with specific camera angles

#

i'm at -1 | -B in this video, so not very far out at all

lapis dune Apr 24, 2026, 2:27 PM

#

Hey Zack! Is this and old BP from a previous version or is that made from scratch?

vocal dawn Apr 24, 2026, 6:44 PM

#

made from scratch, just placed those trains down

#

I can try some more things today to see how easy it is to reproduce

vocal dawn Apr 24, 2026, 9:55 PM

#

happens consistently with a setup like this

lapis dune Apr 27, 2026, 5:24 PM

#

Hey Zack! Thank you for that last video, I was able to repro it very consistently. I'll be writing a report about this issue
