So I was going to Smithville dam from Black River. I had:
- Azov truck.
- Utility trailer attached to it (via "attach trailer").
- Sideboard trailer attached to utility trailer with rope (whinch).
After going through the tunnel and getting to Black River I found out that sideboard trailer got detached on it's own (so I had only utility trailre behind me).
I guess this happens with everything that's attached with rope to your truck (or maybe only to your trailer).
Please fix this!
