Not sure if this is an artifact of a previous recipe for the EV Energy Hatch that was present in a past GregTech version, but in the quest book it's listed that Tungsten Steel is a requirement for crafting them when it isn't.

Hi. While fixing this issue on the Quest Book, I realised that even though the recipe for EV Energy Hatches and EV Dynamo Hatches doesn't require Tungstensteel, when scrapping them with an Arc Furnace or grinding them with a Macerator, Tungstensteel is still one of the outputs. This allows for the player to get Tungstensteel in an unintended and unintuitive fashion. @Deepacat should we make a new issue for this?

This no longer occurs with GT 7.0.1 (the recycling issue)

Sounds good, then it's not an issue anymore.
