Cows from older saves come with milk, not milk_raw, leading to errors

[jeremyshannon]

Describe the bug

Milkable animals were switched over to producing milk_raw, but the game doesn't seem to migrate old saves correctly on this.
Thus you get "cow/sheep/whatever is milkable but has no milk in its starting ammo!" errors whenever they enter the reality bubble, and when you try to milk one, which produces nothing.

Steps To Reproduce

Steps to reproduce the behavior:

1. Make a player with a gun, magazine, and some ammo.
2. Try to aim at a wall.
3. There's no way to increase aim level.

Expected behavior

Old saves should be updated.

Additional context

Looks like it won't take my zipped save for some reason. Uploaded to a free file host: https://anonfiles.com/X9j9H6Xcn8/HartwickCounty.tar_gz
