Sorry, tried to fix it but couldn't spend the time on it. As I don't play anymore, the mod is deprecated.
If anyone wants to give it a shot to fix. There is multiple problems:
- Any kind of new material in Spaghetorio does not have a weight. This crashed hot-metals. Way to fix it would be that either hot-metal fixes this or a generic method that everything that does not have a weight gehts weight 1
- Spaghetorio removes the casting-pipe-to-ground (+ other stuff but it doesn't break anything). Hot metals has a compatibility for this. That needs to be fixed in hot-metals
If anyone wants to pick up the mod, feel free. Most of the fixes would need to be applied by hot-metals. Any new material added by Spaghethorio obviously wouldn't be supported as it would require custom image generation but it is already pretty complete for anything added until April 2025.
