Not sure where to post this, but when creating a scenario and placing a fluid wagon Mk3 then decouupling the last and middle tank the game crashes.

EDIT: this also happens when de coupling first and middle

I don't see how this could be specific to fluid wagon 3, it's literally a clone of the vanilla fluid wagon with a couple of stats tweaked.
Try post a bug report on the main bug reports forum.

You're right, this issue is on all 3 fluid wagons including the vanilla. I posted on the main forum.
