New Delve catch up mechanic can spawn explored nodes disconected from other explored nodes

As title says, new Delve catch up mechanic can spawn nodes that are marked as "explored" but disconected from other explored nodes. This happens at the very end of "catch up shaft". I can travel to this node from the mine encampment same as to all other already explored nodes. My character is level 87 and "catch up shaft" is the deepest part of my Delve. My bug report reference number is 240 774 226. Below i provide screenshots of the bug and my bug report reference number.
