I have 4 quests in a row, where three are PRE of the first. If you click on the first to skip, you do get the message that the following quest will also be skipped. You click on yes (or something like that). But the guide still stays on the first quest. Here is what I have.

A Prisoner of War |QID|11973| |N|Borean Tundra (70-72) - Transitus Shield, Coldarra. The next 4 quests are Nexus quests and requires the dungeon finder.| |Z|Borean Tundra|
A Have They No Shame? |PRE|11973| |QID|13094| |N|Borean Tundra (70-72) - Coldarra. This is a Nexus quest and requires a group.| |Z|Borean Tundra|
A Quickening |PRE|11973| |QID|11911| |N|Borean Tundra (70-72) - Coldarra. This is a Nexus quest and requires a group.| |Z|Borean Tundra|
A Postponing the Inevitable |PRE|11973| |QID|11905| |N|Borean Tundra (70-72) - Coldarra. This is a Nexus quest and requires a group.| |Z|Borean Tundra|

Thanks for this, will look into it.

Did some work with step skipping. Not sure if this is solved, but marking as resolved until told otherwise since I'm betting that if there's still an issue, it's something else going wrong.
