Greetings!
Short story, I was attempting to use both of these mods in junction, but, they are incompatible. I don't expect anything from you, just giving you a heads up about it :) If you think I should report it to the other modder instead, also feel free to let me know. Thanks again for doing what you're doing.

Whenever I would attempt to use the Vehicle Wagons Feature, such as using the winch or using the ramp, it would crash to main menu. It would send a autodrive permission error:
The mod Vehicle Wagon 2 (4.2.2) caused a non-recoverable error.
Please report this error to the mod author.
