Please watch the video for more information, but these are the fixes for earlier versions of Minecraft. The fixes include funnels with a filter set don't pickup items off the ground, Gantry carriages break when they move back and forth too quickly. You can mix and max the fixes with the original farm for a faster speed if you want, but this should be more stable for all gamemodes.
silverfish wont go into the small slot where they are killed by the deployer. Most of them (90%) stack up on the belts and wont be brought to the depoyer! Very sad. Any ideas how to fix?
