I completed the MQ on a cp3600 template alt before speaking with the Hooded Figure, and working through the Harborage quests. A few glitches in the delves, but they could have been connection issues at my end (very stormy today).
However, at the end of 'Council of the Five Companions' I received this dialogue:


I completed the dialogue, checked my map to confirm I had in fact completed the Planemeld:


Then exited the Harborage and ran up to where Varen usually spawns in next to the guard at the foot of the stairs into Daggerfall. No Varen, no quest updates, nothing, and then my game crashed.

I logged back in, and found my Journal now prompting me to return to the Harborage to proceed with 'God of Schemes'.

Because these quests can't be abandoned, I can't check whether this is repeatable without redoing everything on a new alt (I really want some Crown Store 'quest reset' tokens, even if they're only for the PTS!)

Is the 'but first complete the Planemeld' dialogue supposed to show even if you already have? Or should there have been a variant of the usual 'I'll call you when the time is right' line to complete this quest?
