Stuck in Act 4 - The Siege

[Alectai]

Posting this here in case someone has a workaround, but apparently the Warp Route that gives you access to those systems just west of Furibundus for this Main Story Quest just don't materialize when they're supposed to. I could just create a route going there... If I had two more Navigator's Insights, but I've explored the entire map.

I don't suppose anyone knows a way to scrounge up a few more? Do I just bounce between unsafe routes for a while and hope I get an event that gives some?

[Westheimer]

The same problem, there are no points to plot a new route, and it is impossible to find a passage from any system in the neighborhood (

Same thing, no route...
And I dont understand, did I whole aeldari quest when killed homunkul and saved eldar from posessed rogue trader. In journal ot looks like completed but doesnt vanish

Travel yellow (1) routes, there should be an event giving 10 points.
