Monster Name:

Steps:
- Became Rank 6 a long time ago, maxed rank with crystals, and began Leaute's Last Wishes
- Returned to game several times, most recent being December 2013.
- Never attempted mission before, worked on other expansions (Leaute's Last Wishes has always been the current mission in my log)
- Spoke to Halver, told me King wanted to see me
- Got cutscene for the end of The Shadow Lord mission (Mission 5-2), where Destin commends me for putting an end to the Shadow Lord.
- Spoke to Halver again, which flagged the quest "Fit For A Prince"
- Every attempt to speak to Halver results in him saying "You are to retrieve a dreamrose from an oasis in the Altepa Desert. Good luck."
- When I zone out and back in, he says it again, but when I speak to him again, I have the option to cancel Fit For A Prince, and then he goes back to asking for the dreamrose.
- Examining the Dreamrose in Western Altepa Desert G-7 gives the message "It is a beautiful desert flower". Sabotender Enamorado does not spawn. I have tried with and without trusts.
- I checked with the bard in the Chateau, and he only lists cutscenes up until Shadow Lord Part II (the one I saw today, instead of the correct one).
- Clicking on the Great Hall gives message "It's locked tight".

I searched the forums, and found someone with a similar issue back in February of 2014, but their post was moved to duplicate bugs, and I have not been able to find any other posts regarding this issue.

EDIT: in the time I reached Rank 6 and flagged Leaute's Last Wishes without doing anything towards it, I have completed Zilart, CoP, ToAU, and WotG expansions. I believe some later parts of WotG involved Halver.
