Modpack: Project Ozone 3; Several Previous Modpacks that I can't remember.

Issue: When the auto-breaker breaks a block that splits into several items (like clay), you end up getting about 1.5 times the items you should if the auto-breaker's inventory is empty.

How to reproduce: Place down auto-breaker --> Place block of clay in front of it.

So far i've tested this with clay and glowstone and it works on both. Since glowstone blocks break into usually fewer than 4 glowstone dust, the duping is slower, but on average you still end up getting more glowstone dust than is needed to make the glowstone blocks that are broken.
