Normally, the Corporea Funnel will place blocks in an inventory that is one or two blocks below it, or drop the item into the world if there is none. This works as it should. However, if the block between the corporea funnel and the inventory is another corporea funnel, it instead drops the item into the world as if there was no inventory below it.
Here's the system I set up.

Here's what happens when the system is triggered. (Also, there weren't actually any grass blocks in the system. Another bug?)

This also happens when the bottom corporea funnel isn't even set to request anything.

And even the bottom isn't even a part of the corporea network.

This is because all corporea funnels are considered inventories. I'll see what I can do.

I have similar bug. When I place funnels by ring up to 2(see screenshot) and activate continualy first cycle of bottom layer of funnels doing normaly, but top layer dont work. In second cycle work only last funnel in top layer
