I have a blueprint I use for loading stations in Krastorio + SpaceExploration + LTN. The filter miniloaders (modded inserters) have their filters set by circuit conditions. These circuit wires are, however, inconsistently placed!
In the below figure, the top-most copy of the unloading station is correct, while the subsequent two have missing connections.

Even in absence of other nearby stations, the issue persists.
Just tested it. The top is an original design. The middle is when one of the buggy blueprints has new contents selected from the top, and then is pasted down. The bottom is a fresh blueprint, which doesn't seem to reproduce the bug.

However, if you take that new (working) blueprint, and then use the "select new contents for this blueprint" button, then it reintroduces the issue, and the wires no longer are place correctly! See below -- the working blueprint was damaged by the use of the new contents button!

So that means the issue is somehow tied to the "select new contents for blueprint" button, which doesn't seem to save the wires correctly.
While this is probably related to that issue, this represents a regression in behavior that worked before the update to wires being saved in blueprints. It also affects more than just a modding interface and presents a problem in vanilla gameplay. Should this really be classified as a duplicate of a minor issue?
