When trying to make a production chain that involves any recipes unique to the immovable buildings on Cerys, such as the Cerys Science pack, the building section is blank. When clicking the recipe to edit it the following error is sent in chat, and a recipe edit panel opens without the machine or beacon sections:

"helmod/edition/RecipeEdition.lua:717: attempt to index local 'factory' (a nil value)"

The actual building section for the recipe is blank, and modules can not be edited. The buildings are also not listed as an option to choose when deciding what building to do a compatible recipe in (such as superconductors or batteries).

Fixed in next release 2.1.3
I added a new rule in admin panel to exclude production machine from the filter "placed-by-hidden"
For recipes with that error remove and reselect it

If you see another recipe with this problem you can add similare rule in admin panel, tab rules and say me i can add the rule in the mod (text from export rule)

mod="Cerys-Moon-of-Fulgora"
name="production-crafting"
category="exclude-placed-by-hidden"
type="entity-name"
value="cerys-fulgoran-cryogenic-plant"
excluded = true
