On RB05 - Red Bank Newspaper Shunter, I have got to the part where I have to connect 2 passenger carriages each with a Buckeye, no matter what I try to do the 2 carriages will not couple, one buckeye locks in the up position, I then use a buckeye to connect the 2 trains together only they won't couple am I going mad as I have not come across this before, people will think just turn on Automatic Coupling, that's all well and good but it still does not answer my first point that the 2 passenger carriages will not couple. Class 08 BLU - shunter Northern Trans-Pennine
I think some coaches were broken in the last update, if I spawn 2 Mk2 coaches in free roam and try to couple them, they just bounce off each other and refuse to couple
If there is an uncoupling bar for the buckeyes try operating it, it may be that the buckeyes are not open. As fatboy#9769 said, some Mk2s aren't working as they should, this includes the Flying Scotsman mk2's that don't connect to anything
