Okay, one more test for clarification (let's play problem solving Factorio outside of the game for once :D).
Factorio 0.18.34 (build 52900, win64, steam)
Cursed-FMD 0.1.2
I launched new Freestyle game without any mods (at all default settings).
Saved game, enabled Cursed FMD, reloaded save.
I then placed free Burning Drill on an Iron Ore patch and tried to use filtering tool on it and got above error and game crashed to main menu.
I didn't unpack mod's archive. I play default (English) language (I mention this in case it's barely relatable, since bug is about GUI and we look for any differences).
