Minor Weed that spawns at roundstart not accepted by Sketchy

[Studenterhue]

As the title says, Sketchy, the merchant at the diner who sells pod parts and drugs, does not buy any weed that spawns at roundstart, like the leaves that spawn in the RD's locker or the weird little "Floorpills shrine" next to Cog1's Janitor Office. Instead, you get messages like "<ERROR> Item not in purchase database" and such. Weed harvested from a cannabis plant is perfectly acceptable. 

Perhaps related to the issues with selling gold?
