Many thanks for the quick fix. I will check it after upgrading to Factorio 1.1...I am just waiting for some other used mods to be upgraded to 1.1...
I have one further question... I just saw, that circuit wires connected to the "silo combinator" are not built after blueprinting.
Please can you check it? Sorry, that I didn't told it in my first message!
Thanks in advance!
