[Bug 1.2] Multiplayer Crash with STZ-VP 3

[SirLANsalot]

- PC/Mac/PS4/XB1: PC
- Vehicle/Tool/Model/Object: STZ-VP 3
- Issue: Crash/Freeze
- Single- or Multiplayer: MP
- Steps to reproduce: Attach to the low loader, then separate the two pieces, drive forward a bit, then back up and reattach. Then Detach from the whole unit, and the server will freeze/crash. This works in both Dedicated and Hosted MP (you can do this yourself if you make a MP game).
- Does it happen on a standard map without mods yes/no: No mods, all maps.

Ya this ones a doozy, found it by accident while playing on a new save kept crashing the server after moving my cotton harvester to a field.
