Baku Cars stopping at end of straight

Sorry to hear that, that's got to be the worst bug to encounter. Something unusual is happening at Azerbaijan as it had these issues during the launch also.

Do you have any information about exactly where it happened? You said the first corner but if you had footage (or if anyone else has footage, because I know it's happened to others) that would be really useful.

I'll also run some races there next chance I get to debug it and see if I can catch it.

Whatever is happening there isn't happening in most races or any tests I've run. The track file itself can likely fix it which means I can probably do a re-export once the cause is known. The challenge is identifying the cause, it's proving quite elusive so far. It'll be something in the structure of the track and how it's interacting with the physics engine.


That's quite a useful description. Did it just stop on the start/finish line? Or a grid slot?

This sounds like some of the issues iRacing had back in the day. Did it look anything like that?

Anyway, this has to be fixed urgently. I'm working on it today.

I did consider it, but was able to quickly find some problems and fix them (twice). Each time the situation looked fixed, then it got live for a few days and someone encounters a new issue. So it's increasingly rare, but not gone, sadly.

It would really help if anyone could capture a video of this, to help me understand what's causing it.

Was there a specific lap number where it would happen? Did it happen on pit in or pit out laps by any chance? or always 1 lap after a pit stop etc.

I am thinking there could be a pattern related to the car moving between different sections of track (it can sometimes impact car behaviour).

A quick progress update: I'm now able to reproduce the issue in a dev environment, so I'm getting closer. I also know roughly what the cause is likely to be, it's only 1 of about 3 things given where it is happening (on the start line).


Agreed, I can only apologise until it's resolved.

I've pulled a late night to get this done, but it looks fixed.

This will change how cars behave on ALL tracks, so please follow up if you discover any issues. Races from 03:00 UTC will use a new simulator with quite significantly refactored handling of this. It was solvable with a change to the simulator, not the track, so it's a global change.
