Might it be possible to get a blacklist added for the Autonomous Activator, of blocks it will not work on? I'm setting up a skyblock server, with the
Ex Nihilo mod, and with just 4 Autonomous Activators, and one Igneous Extruder, it's possible to almost completely automate gathering ore/diamonds, etc. (I.e., for less than 30 iron, 5 redstone, and some copper/lead, you literally never have to think about resource gathering again)
I really don't want to ban the Autonomous Activator, as it's a fun block, and while powerful, isn't OP in any other situation i know of but with the Sieve from Ex Nihilo, but with no blacklist to control what it can interact with, I don't see much else in the way of options.
