Loading a save from MacOS results in "Couldnt get trait"

When loading a save created on MacOS, Windows client crashes:

Looking through the save file and one that I just created on Windows, the difference seems to be caused by each platform using their default slash character.

MacOS save using foreslash:

"worldTraits":["traits/MetalRich","traits/GeoActive"]

Windows save using escaped backslash:

"worldTraits":["traits\\GeoActive","traits\\MetalRich"]
