Sportsman coupling problems

[NKP1]

I give up on this. Spent all afternoon trying different locos and passenger cars and all I'm getting is either it won't couple or the loco passes right through the passenger car or it decides to suddenly bump and go flying in the air. The C&O SD-40 won't couple at all. The B&O loco will couple but requires a lot more brake and wants to drift on less throttle. It doesn't matter if I'm using the older IHH or the newer RSC versionss. The dome car refuses to couple to the baggage car and it placed together in a scenario edit explosively uncouples from baggage car. Results are the same. Unplayable.

A lot of coupling problems, from what i have read on forums, are caused by not having the Kuju provider boxes ticked, as a lot of rolling stock depend on the 'default' kuju coulpers. Just in case.

Kujo is ticked. And I'm just tired. Got a headache and a nasty cold. going to bed. sort it out later.
