Hello!
Are you using Krastorio 2 on Factorio 1.0 or 1.1?
If you are using it on Factorio 1.0 I will try to find the bug, but if you are using Factorio 1.1 then Krastorio 2 already contains the changes for that, so if they do not work it will be more complicated.
Let me know (and sorry for the wait)
