Currently unable to place cargo wagons in my game; Normal placing destroys it and the bots aren't able to put it on the tracks. I was able to put down the train but that was it.
Maybe mod related so below is a condensed list of mods
Full Bob's mods
Full Angles mods + smelting
Angles addons - ore silos, pressure tanks, and warehouses
Foreman
Only Robots
Reactors
Resized Buildings
RSO
Squeak Through
Yet Another Resource Monitor Fork (Also can't use this either)
Please let me know if you need any other info.
