how can i burn grassweed in the fireplace on the sims medieval?

Answer 1

Your sim needs to be wearing the fresh linen (click on the wardrobe if you haven't done so already) and have three grassweeds in their inventory. The option will appear when you click on a fireplace. Don't bother buying an expensive wardrobe or fireplace as it doesn't affect anything.

To sim up: the sim needs to be WEARING the fresh lining and have THREE grassweeds in the sims inventory.
