Suggested Route is over 100km longer and no alternatives presented, forcing the issue results in a failed route

Planning a trip from Hornsby NSW to Mudgee, ABRP offers only a single option via Cessnock which is 380km with a 28 minute charging stop, total trip duration of 4h 50m. A more direct route via Lithgow is 280km and 3h 30m so with a similar charging stop duration is an hour faster and 100km shorter. ABRP will not suggest this as an option.

Worse, adding Lithgow in as an option results in a “no valid plan found” and attempts to route via Goulburn instead - a trip that while possible is now 540km and 6h 30m!

For some reason ABRP seems to think that two highways through the blue mountains do not exist. I suspect that the fact that one of those is partially closed is affecting the other, and therefore avoiding driving through the mountains at all.
