I'd like to see a grass ladder.
The mechanic would be that it's not permanent like the grass foundations. It would, over time, dry and have a chance to break when being used.
Just as the title says. I haven't seen a dew drop spawn on a leaf in some time after the patch. I also started a new game. I've been filling my canteen with juice. About to build a dew collector so I'll update if that works.
