[0.16.51] Crash trying to connect rolling stock: "this->state == RailConnectionDirection::None was not true"

[Nate_the_gamer_24]

Heyo

So my game crashed (that's why I'm posting this{stupid me})
When I was playing in a scenario I tried to connect the rolling stock of a train with a cargo trailer full of water barrels to some other cargo trailers with barrels.

The game froze for a second and then it said to send in an error report
I had no idea what happened but this is the first time it crashed when I tried to connect rolling stock

Thanks for the report. I've seen this error a few times but nobody knows how it gets into that state which makes it near impossible to get this fixed.

If someone knows of a way to take a new save game and produce this error that would help a lot.
