A350 slides automatically on stand

[checkyoursignal]

Hi:

The A350 automatically slides backward after being positioned on the stand. This movement also occurs post-flight when chocks are applied or the parking brake is set. As shown in the attached photo (taken 1.5 hours after engine shutdown), the chocks, aircraft, and GPU moved together as a single unit, rendering the chocks ineffective.

The "ice cream cones" marking the original engine position clearly show the engine had moved from its initial location. This issue persists in version 1.0.7 and has not been documented in any development blogs.

Thankyou
