Greetings.
This mod uses art from Krastorio 2, and was released under the MIT license. As such, it is breaking the Krastorio 2 license terms. Krastorio 2 is licensed under GNU GPLv3. This license allows derivative works such as this, but only if you release it under the same license. See section 5 in the license text.
Please change the license to GNU GPLv3, include a copy of the full license text in your mod, and delete all of the mod versions that had the MIT license.
Thank you!
Edit: Upon inspecting the mod files, I have discovered that the mod doesn't have a copy of the MIT license either. So this mod was actually released without any license whatsoever, despite what the mod portal says.
