Unsure if this is happening with others or some kind of setting I am unfamiliar with in Factorio, but after this morning's update (1.1.19), the power connectors for all of the rails are now showing when previously they were hidden.
If this is unintended, then something to look at for a bugfix, otherwise I would recommend adding a setting to disable showing these connections as with the previous behavior of the mod (Or as mentioned above, perhaps something I personally don't know about, in which case, any way to turn these off?).
Thanks!
