In my current Vodyani game I can't use a starlane that has ben envined by the Unfallen. When I try, there is a tooltip telling me "there is no path to this node, your ships need free movement (warp)". However I do have researched baryonic shielding and I click on the starlane, not a node.  I am in cold war with the unfallen and they have open borders with me. Is this a bug or am I missing something?

Can you post a save?

sure,

here it is : Vodyani80starlane.sav

Thanks!
