What did you do?
I smart replaced a small power pole with a medium one.

What happened?
The medium power pole didn't connect to another one that was in its range (but not in the range of the small power pole that was there before).

What did you expect to happen instead? It might be obvious to you, but do it anyway!
I expected the medium power pole to connect to the other one because they were in the wire range of each other.

Upload screenshot OR save.

It may be just simple case that they do not connect because one of them has reached its "wire capacity" (equal to 5 cables going to/from one power pole)

Can only duplicate on poles that have existing power connections. Poles with no power connections appear to recalculate their connections when replaced.

Ok. confirmed. Attached save (with replay). When placing medium power pole there is visual hint there will be wire conecting two poles, but after placement there is none

It's a not a bug.
Fast replace will not change existing power connections by design.
You need to rebuild the pole to get new wire connections due to increased range.
