Rain Collectors
The Rain Collectors should have appropriate in-game titles.
The square rain collector should be named 'Lesser Rain Collector' or something like that to reflect the capacity difference between the two available entities.
Also, the in-game description should indicate the capacity for each Rain Collector.
I didn't find out until I looked on the wiki that there's a technical difference between the two Rain Collectors. After I disassembled the square Rain Collector I only got 2 planks back at Carpentry 8 so that was frustrating.
Also it would be appropriate if the bigger "barrel" Rain Collector graphic/model had the trash bag visual incorporated somehow (like the square collector), considering that it's a part of the crafting recipe.
