Hello.
I am the maintainer of Krastorio 2. This derivative violates K2's license, as it has been released under MIT. K2 is licensed under GNU GPLv3.
You can keep this up, but please change the license to GNU GPLv3, and note any changes that you have made in the source code. Otherwise, I will have to ask the Factorio team to take this down.
Thank you!
