See this picture Maybe other mod machines will do the same, so we have to strengthen the judgment of the concept of container, Please forgive my bad english. @Resourceful-Bees

Is this the only machine that exhibits this behavior?

It has been found that the RS pattern_grid, interface and the attached ‘Extra Storage’ assembly also be mistaken for containers, but they do not have this bug.
The probability of this bug is that the author of Colorful Bee did not do a good job of synchronization, but if quark did not regard it as a container, we would not find it.

Relevant classes appear to be
com.resourcefulbees.resourcefulbees.client.gui.screen.CentrifugeScreen,
com.resourcefulbees.resourcefulbees.client.gui.screen.MechanicalCentrifugeScreen,
com.resourcefulbees.resourcefulbees.client.gui.screen.CentrifugeMultiblockScreen.

I'm trying to make sense of what is supposed to happen here so I can figure out where the bug in our code is and fix it. I get it's duping the inputs but I'm not sure what's supposed to be sorted or how the sort function works.

We need to add the pattern_grid processing type of RS to the blacklist too. Although there is no bug, but it overlaps the GUI. ：）
