You know, if Trash 2 uses chemical science pack to research, then why would Auto trash require the same science pack research done while one of its prerequisites already uses the pack for it? It seems kinda strange oversight;;

Other mid-tiers of number upgrades do not get all the pre-requisites as that should already be obvious from science pack icons under the technology icons, and it would probably make the technology tree look way too messy.
