Fluid Discretizer not discretizing within subnets

[Buschie]

version: 1.3.7-gtnh -> pulled from 1.7.10 build

Visual representation of the bug:

Main net to subnet connection uses dual-interface to storage bus and dual interface to fluid storage bus connections.

Note: there is a work-around to be able to see the drops in the sub-net using a storage-interface pair with a fuzzy card for drops, but as the fluids are discretized in the main computer, and not the sub-net, fluid crafting recipes cannot be completed.

The crafting-breaking behaviour can be reproduced by creating any crafting auto-crafting recipe within the subnet which creates a fluid and exports it to the subnet. Exporting the crafting output to the main net breaks the recipe too.
