**Game Version**: KSA v2026.5.3.4264 (Latest public build)
**Platform**: Windows 11 (PC)
**GPU**: NVIDIA RTX 4060 Ti | VRAM 8GB


#### 1. What I was trying to do
I was performing an EVA (Extravehicular Activity) with a crew member in a stable circular low Earth orbit (LEO), then attempting to return them to the crew cabin.

#### 2. What happened instead
Immediately after the crew member re-entered the capsule, the game began spamming repeated errors in the console:`System.Exception: Populating analytic states from outdated kinematic states for [Vehicle Name]`The error loop froze the vehicle simulation: time warp could not be used, and orbit data appeared to be unresponsive(Please see the attachment for details).Crucially, the error messages **only stopped appearing after I manually changed the vehicle's attitude using RCS thrusters**. The physics simulation recovered as soon as I made even a small attitude adjustment.

#### 3. What I expected to happen
After the crew member returned to the cabin, the vehicle's physics and orbit simulation should continue normally, with no exceptions thrown, even in a stable, non-rotating state.

#### 4. Steps to reproduce
1. Perform an EVA with the crew member, then have them re-enter the cabin.
2. Observe repeated exceptions appearing in the console.
3. Use RCS thrusters to change the vehicle’s attitude slightly.
4. The exceptions stop immediately, and the simulation resumes normally.

#### 5. Additional context
- The issue occurs on the latest public build, with no mods installed.
- The orbit was stable and non-rotating at the time of the EVA and return.
- The problem only resolves after an active attitude change; waiting or warping without input does not clear the errors.
- Attached are screenshots of the error log and the vehicle’s state in orbit at the time of the crash.

Hello!

Thanks for the bug report(s). Just a heads up, bug reports for the game go in KSA Bug Reports.

@Terra Incognita Could you move the thread? Thanks.
