Hello, I encountered an error when starting the game.

모드 불러오기 실패: mini-machines/prototypes/copy-final-fixes.lua:69: object_type is missing for Data/electric-furnace
stack traceback:
[C]: in function 'error'
kry_stdlib/stdlib/data/data.lua:548: in function 'Data'
kry_stdlib/stdlib/data/data.lua:377: in function 'copy_fields'

[C]: in function 'require'
mini-machines/data-final-fixes.lua:1: in main chunk

Do you have any mods that modify the electric furnace, or add new electric furnaces?

Assuming this is a duplicate of this issue with EV Refining, should be fixed as of v9.3.2

Sorry for the late reply X)
I've been aggressively expanding my mod list, so I've been a bit overwhelmed.
I removed EV as you suggested and it works fine.
And I'm playing almost all of your mods.
This time, even Planet Mod. Your mods make my Factorio rich and enjoyable.
Thank you very much, Kryzeth

No worries, and I'm glad you've been enjoying them! Though you don't have to disable EV Refining, it should be compatible moving forward, as long as you update this mod to v9.3.3
