In the latest release of Create, 0.5.0, there have been some changes to how SU can be generated. Namely, Encased Fans no longer generate SU period, they are only used as fans now. Also, the Furnace Engine has been removed completely so no super crazy SU generation. The quests need updated to reflect this.

Using pack version 0.4.22 which is the latest version available on CurseForge as of 07/17/2022. Reference below for screenshot of quest stating that the encased fan can be used to generate a SU. There is no quest for the Furnace Engine, that's a mistake on my part.

Please make sure you are on the most current version of the pack before reporting quest issues

Oh I understood that the fan still had issues and will pass it along, but you can see why I suggested you check your pack version

Oh yeah, absolutely, always good to double-check and since I mentioned the Furnace Engine, it's only fair to assume. That's what I get for not paying close enough attention and realize the Furnace Engine wasn't there, I swear my eye saw it, lol.

With any kind of changes and updates to mods, it will take some time reworking anything that is attached to it. I removed the Furnace Engine when I got word of it disappearing, but I'm sure we'll find plenty more quests needing to be changed as we continue to see more mod updates!

I'm making the change as we speak, and it will be updated in a later version. Thanks for the find!
