Hi, unfortunately, from the last Krastorio 2 and Space exploration updated this mod seems not more compatible with them. I tested only with K2 and SE actived and I received the following error message:

Error ModManager.cpp:1560: Error while running setup for recipe prototype "kr-matter-plant" (recipe): Duplicate item ingredients are not allowed (fu_materials_KFK exists 2 or more times).

Thank you for your work
Best regards

I got the same error message, appears if there is a mod 248k + krastorio2 and the "recycling" option is enabled.

version krastorio2 - 1.3.14
version 248k - 1.0.29

For me it is running as long as I don't touch the 248k option: "Enable Overhaul mode" which inserts 248k in the vanilla/K2 progression chain which includes techs and recipes to.

I assume that smth. has changed and should be looked over again.

What I found out was to comment out lines 275 and 276 in 248k_1.0.29\scripts\krastorio2\overhaul.lua

Lines should look like this then:

--{"kr-matter-plant", "fu_materials_KFK", 12},
--{"kr-matter-assembler", "fu_materials_KFK", 8},

Question here is why are only these triggering this error and not e. g. "kr-advanced-chemical-plant" which uses 6 times of "fu_materials_KFK"? But this temp fix could help you guys out to play with 248k + K2 + SE :)

Thank you so much, seems that it's working.

You are welcome but keep in mind that you have then the original recipe for these two machines until a fix is released so keep that in mind.

After the updating the Factorio version from 1.1.74 to 1.1.76 (and have mods updated too)
This comming (game cant loaded)

The error seems that same that happened to me, but I solved it following the instruction above.
I'm playing 1.1.76 and all mods updated, all it's work fine, maybe with the download of new updated you need to re-apply these changes?
