Can't select "Red Onion" as payment on barter stands

[Pills]

Yellow and leek work just fine, but trying to set the requested payment as red onion only gives the option for "onion" rather than explicitely red.

Have you character learned about red onions?

Maybe there could be error message if thats the case.

Huh, turns out I hadn't learned it on the character I was using. Fair play
