Processor dosen't recognize different buckets

[Qetrab]

Issue description:
When I was working with autocrafting at some point I had to use filled buckets with different fluids from various mods. Unfortunately as shown in the screenshot processor doesn't recognize fluids from mods. I used 'examine item internal' opcode for slots 0-3 and then printed themout in the processor console.

Steps to reproduce:
Fill bucket with some fluid and create a program to examine item internal or use item equality opcode.
