Boxcar blues

[Ghost42]

After a seamless upgrade I decided to sort out my main project, modify/adjust some track and put the consists back one by one.
All has gone well till I added boxcars for loading 'paper roll bleached', CTD.
I swapped out the boxcars for ones with a later version, no change.
Changed the MIN and loco, no effect.
Deleted the boxcars and all is back to normal.
Do you have a favourite boxcar that will handle paper roll and general goods and behave itself, fictional route so anything goes (got to keep them dry)

After spending hours swapping out Boxcars I switched a flat, managed another half mile before CTD, I'll bypass that industry and carry on.

One of life's great mysteries, Enter Mr Holmes!
What other scripts could I see around the industry that could be interfering, MINs set up for woodchip and paper roll - delete, CTD, signals - delete, still CTD, switches - lay out a length of track, signal at the end - CTD, what is left? the factory itself - swap out for the identical 'Factory 8 gengoods' - solved!
Take off my deer stalker hat, blood pressure back to normal.
