I have been going through the Technology section of the quest log, and toward the end, there is a quest that requires you to build an External Heater. Clicking the item doesn't bring up a recipe, nor does searching JEI. When I looked at the IE wiki I found the recipe, but in game it creates an Induction Heater. I crafted it and it did not complete the quest.

I'd like to see that quest changed so it is completable.

Perhaps either change the requirement for the quest (which is probably easier idk), or return the recipe for the external heater.

This is the recipe screen for the Induction heater, which also has an alternate recipe.

Thanks so much for posting. This happened because the induction heater from create craft and additions replaced the heater from Immersive, but I didn't realize that when I added the mod. So the one from IE was uncraftable. Surprised this hasnt cropped up till now! It's fixed for the next release.
