I was trying to give one of my tribe mates her 2nd prize in our tribes art contest, which were 3 bunny furs, 4 milks, 5 snowstorms and 5 spraycans, yet I couldn't put the Snowstorms and spraycans in the trade!
Why?

Did your tribemate have the max amount of snowstorms and sprays, by any chance?

I don't know, I'll ask her
