About a week ago Py changed the internal name of the Wood Processing Unit and since then I've been unable to add any of the recipes of that machine into my production blocks, with an error indicating that Helmod didn't find a valid assembly machine for the recipe.

+1

can you try?
open administration panel of helmod in the cache list tab:

• delete "HMRecipeSelector"
• delete "cache" under your name
• delete "translated" under your name

after that retry Wood Processing Unit

For me that just makes the recipe selection menu go blank and not find any recipes for anything, and if I allow the cache to be regenerated I still get the initial error.

reapply blank filter, some time is blank but there are a filter

For me deleting cache does not work. Still there is error.

One thing to add: i have selected the TURD for Fastwood Forestry : "Selective cutting heads" (the one which makes cutting Log to Wood faster and doubles output (maybe that is causing the error?)).

you are check if there is the problem in a new game?
if you can share your save, I can check if i find the problem.

In new game it works.

if you can share your save, I can check if i find the problem.

Here is my save: https://limewire.com/d/zS7bc#c8woE7Vx1j

Thanks

^ reproduction steps in my save:

1. Open helmod.
2. Add new production line for wood (recipe: "log-wood-fast") - you will see log with error:

227.758 Script @helmod/model/Player.lua:47: helmod/data/ModelBuilder.lua:431: attempt to index field 'factory' (a nil value)

I found, it's a default of machines

• open Preferences panel (ignore error)
• open Default of machines tab
• delete wpu-handcrafting

@Helfima this one worked - many thanks!

fixed in v2.1.23
if default of machines not exist is automaticaly delete
