Has everyone got the code for cave hemp?
If not, then it'll glitch, however I made it for the lulz of it, it's edible, you can make drinks AND clothes out of it, making it a very versatile material. Also, it's a dye product, so you can dye the clothes a plum colour, which is cookable, as is the extract, which is a hemp oil.
Add this to your matgloss_plant.txt or you can't run the fortress at all, or with glitches, I've not seen the effects yet.
