Career mode: LUA error when delivering mixed cargo

[Futt]

I picked up a 'parcel' job from the steel mill, delivering Dangerous Liquid to the refinery on the pier. I had lots of spare tank capacity (MD70 + Short Tanker trailer) so I filled up more from the bulk cargo tab. Mission list on the top right correctly shows two jobs.

When I arrived at the destination drop-off point and clicked the button to deliver the cargo, I got the attached LUA error and nothing was delivered.

EDIT: Tried again, this time *just* picking up the job and not loading any bulk cargo - got the same error. Only loading bulk freight seems to work fine though.

I've encountered this issue twice playing on Italy, i've brought a Water tanker trailer with a hookup end, attached a trailer with steel tubes and when arriving to deliver, menu just disappears & nothing delivers.

i've even tried unhooking one to see if that helps but nothing so ya end up having to abandon both loads.
