I have a save saved in 1.1.100 that has trains in it. When I open the save in 2.0.72, most of the cargo wagons get colored with the locomotive's color. This seems to be a bug, as wagons had no color in 1.1.100 and there is no UI to set wagon color in 2.0.72.
The trains in 1.1.100 appear like this:
The save, saved in 1.1.100:
When loaded in 2.0.72, the trains appear like this. They seem to use destination stop's color just like the locomotive. It's also a bit sad that the trains switch to "use destination stop color" and lose the hand-picked colors.
The migrated save (the previous attached save, loaded in 2.0.72 and saved):
[2.0.72] cargo wagons become colored in saves migrated from 1.1
Re: [2.0.72] cargo wagons become colored in saves migrated from 1.1
Thanks for the report. I can fix this, however it's only going to fix saves when migrated from 1.1. Once a save is in 2.0 or later the migration is already done.
If you want to get ahold of me I'm almost always on Discord.
