Just updated Factorio and LTN and suddenly found my copper stations 8 - 13 was in network id 128.

At closer inspection (nose 3 inches from the station combinator and input light) - two wires!!!
Somehow I had managed to get both red and green wire from the constant combinator to the input light - and when the station ID in the combinator set to ID 64 LTN adds them up and assigns station ID 128 (and that does make sense too).
Not sure if this was changed in latest update (or if I just entirely missed this for the last few days

Anyway - keep an eye on what wire you use - and stick to the same on all stations. At least you will not have to fix all of them like I do...
