This suggestion is pretty simple. I feel like it would nice to be able to get vines from C Ward and/or from fishing. If A Ward players can get the Twisting & Weeping Vines, then I think it makes sense to let players get regular vines!
An added benefit is that this will allow players to make mossy cobble/stonebrick, which I think would be a fun aesthetic feature to be able to use.
Thanks for reading, make sure to wash your hands.
