I have 9 obsidian pipes at the bottom of a mob spawner with autarchic gates on them. Each set to, IF redstone signal off, THEN energy pulser.(The gate indicates it is pulsing) But it will only pick up items that land right on top of the pipe. This build worked recently and I couldn't find any
thing resembling this in the changelogs. I hope it's a bug and not a change, but if it is could you give me a heads up please.

Thank you sirs!

Try multiple pulsars.

I can confirm the use of an Iron and gate with the same settings worked. Thank you sir. I'll add I like the change as it is more balanced.
