Jumping Tracks

[Wywurrie]

- PC/Mac/PS4/XB1: PS4
- Vehicle/Tool/Model/Object: GRIMME VARITRON 470 PLATINUM TERRA TRAC
- Issue: Rear tracks jump up and down as if they're constantly colliding with the field surface, but it only happens with an AI worker (tracks work fine if you drive it yourself)?
- Single- or Multiplayer: Single
- Steps to reproduce: (In farm manager mode) Hire Ai worker for SP potato harvester and then leave machine to work on field 19 of the Felsbrunn map.
- Does it happen on a standard map without mods yes/no Yes
