I wish people would talk more about these. I absolutely love the retrievers. I wouldn't be shocked if they're tearing my cpu to shreds but I don't care because they're awesome.Thermal Dynamics in 1.7.10 did this very well. In all, it was an amazing, if under-used, mod. I always thought of Thermal Dynamics as the natural successor to the RP2 tubes with a better built-in sorting system. It even had Supplier logistics capability with the Signalum and Enderium level Retrievers. If only it had auto-crafting and centralized storage data, it would replace Logistic Pipes and probably AE2/Refined Storage as well!
