put back the module in the Em Plant can be cool (no is not for the 50% productivity)

I just landed on fulgura on my 2nd playthrough and noticed this as well ha. I think the mod pulled the modules out of the EM plant recipes. Is that a by-product of the changes? Is it possible to fix? or nah...

I did not disable the recipe in the Electromagnetic plant. I don't have access to Fulgora so I can't test it myself.

Was the recipe available in the EM plant when you were using version 1.0.4 of the mod or did you start using this mod after the release of version 1.0.5 (about 23 hours ago)? Are all modules hidden now or does it only affect the quality modules? I have a suspicion about the possible reason but that information would help me very much.

I actually think this was also in the previous version, as I remember jumping into my no mod save with mods enabled to copy some blueprints and found it funny that the EM plants had no recipe.

All modules are missing, not just quality.

Let me know if anything else I can answer.

That's great, I think I might know the reason. That means it never worked since it was updated for Factorio 2.0. I found another mod that makes additional recipes available in the EM plant, it seems like adding them to the category electronics is necessary. I don't want to push a possible fix to everyone before I'm sure so I would really appreciate your help with a little test before.

1. Open your Factorio folder, the path depends on your operating system, you can find it for Windows, MacOS and Linux here: https://wiki.factorio.com/index.php?title=Application_directory#Locations
2. Open the folder "mods", then unzip the file "CheaperModules_1.0.5.zip". If it worked correctly, a new folder "CheaperModules" should be created. If it worked correctly, delete the CheaperModules_1.0.5.zip file so Factorio gets the mod from the new folder (don't worry, if the fix does not work you can download the zip file from the mod manager again anytime).
3. Open "data-updates.lua" in the CheaperModules folder, any text editor should be able to do that. In line 21 you should see "energy_required = 10". Please add a comma (,) after the number 10, then press enter to create a new line.
4. Copy this into the new line (it should be line 22, please make sure there is no comma to end this line): category = "electronics"
5. Save your changes to the file (Ctrl + S in most editors), start Factorio, make sure you activated the mod and check ingame if the quality tier 1 module is enabled in an EM plant.

If only the quality 1 modules in enabled in the EM plant, all the others are not possible in the EM plant but every module can be crafted by hand and in the normal assembly machines, we have a fix that I can release as an update for everyone.

Perfect instructions, thanks!
Yes that worked as expected! I can now see the Quality 1 module in the EM plant recipe selector. And I can craft every module by hand.
Success!

That's great, thank you very much! Version 1.0.6 is now available on the mod website. You can delete the folder created during the unzip operation in Step 2, then download the mod again from the mod manager as you did before. All the modules will now be available in the Electromagnetic Plants. Hope you enjoy it!

Working perfectly!, I deleted the folder and downloaded the latest update through the mod portal in game. Can confirm it works - all the modules are now showing in the EM plant.
Thanks for being so quick as well! Much appreciated.
