Not sure if this is a bug in Conqueror or in FO4 itself. I am up to the point in Jammer's quest where I take over Sanctuary as an Outpost then I scout out Abernathy as a vassal. When I get the ping that Abernathy is scouted I open my Pipboy to fast travel back to Sanctuary to setup the raid and CTD. I reload, load up the last save, and make my way back to Abernathy and, again, when it pings I scouted it, this time I save then open my Pipboy and, again, it CTD. But when I reloaded the save just after it pinged I was able to open my Pipboy and fast travel back to Sanctuary and it hasn't crashed again.
