Autos'n'Rails
As they say, nothing is more permanent than a temporary solution.
In version 1.18.2, the Automobility mod contains a fix that allows it to work properly alongside the Create mod. This solution is based on the Create mod's identifier being create.
The Create: Steam'n'Rails mod uses similar methods for adding models to Create and encounters the same compatibility issues with Automobility (more precisely, with the included Myron library) as regular Create does. This mod applies the same fix for all mod identifiers specified in the configuration.
