Hi,

Your country covering CS does not make it easy on reviewing what you did but anyway, propose forward on you save your edits per-route, I came across this MTB path Relation History: (SI-C P10-B) Assergi - Castel del Monte (12601445) which JOSM has been reporting since I first touched it as having 3 gaps and sorting did not improve. What I did find is routing from Assergi to Castel del Monte with sections going against oneway directions. That may be fine for MTB riders but then the tagging on those sections need to be told they're oneway:bicycle=no OR the MTB section is parallel mapped to the side of the road if that is what's actually done. Also found a dead end, removed, as it was not specified as first forward and then repeated backward.  Cant believe riders taking a coffee break at an agriturismo. The end result is there's 2 flagged gaps left, They're in the route relation, maybe falsely flagged. I know zero about MTB routing so that's where this issue is handed over to you.

Kindly verify
Ciao
