I can confirm the same issue here.
Our server recently did an updated of mekanism, cofh suite, extrautils & rotarycraft. I am experiencing the same issues with the extractor, but also with extracells using mod fluids (water / lava work, nothing else though) - unfortunately I am not savvy enough to understand if they are related or how to check but I am thinking ore dictionary & fluid registry maybe effected by similar change somewhere (if I even understand that correctly
)? I will ask the admin to change the B:"Force Inter-Mod Ore Compatibility" setting, hoping any new info can help though as the problem seems that it may be larger than just RoC.

Edit 1: Using a custom mod pack - all issues are new since those updates though.
Edit 2: B:"Force Inter-Mod Ore Compatibility"=true is already set in our configs
Edit 3: Just read this on Reika's Guthub:
If you DO have AOBD?
Change "B:RotaryCraft=true" to "B:RotaryCraft=false" in aobd.cfg
