I regret to report a "correction" made to one of the Sebino Lake assets is wreaking havoc on many Italian routes, including the Sebino Lake itself (even though, in this case, the role of electrified lines is marginal).
In the config.txt of the asset Trave FS quadrata,<kuid2:81791:38001:1>, the tag "istrack = 1" has been changed into "istrack = 0" changing the asset from a track into an ordinary spline.
Even though the asset is not a track intended for running trains, the author made it this way since it is a transversal girder used to attach the supports holding the catenary wires.
This is how the girder/supports complex should appear (with the girder istrack tag set to "1"):

This is how it appears in game: the supports, lacking the transversal track, aligned with the real track running below the girder.

I am pretty sure this mistake was caused by nothing else than lack of familiarity with the asset peculiarity. This issue, however, is causing big troubles in almost any Italian electrified routes (i.e. most of them), so I recommend restoring the value of the "istrack" tag to "1".
Kind regards
