Thank you very much for compiling the threads on this topic. :)
Full disclosure...I made the mistake that introduced this bug in Reaper's Choice, and I apologise for the inconvenience it has caused you.
EDIT: Unfortunately I was overly optimistic and we cannot hotfix clientscript, only server script, and it's a logic error in the client code that builds that list of reaper tasks.
So unfortunately to fix this Reaper Choice UI bug will require a game update. So I don't think we'll be able to resolve it until Monday at the earliest. :(
I implemented a fix for it yesterday evening. It's awaiting testing.
Assuming it passes QA, and assuming it is hotfixable, it's a temporary fix that'll make all Reaper's Choice bosses available, to minimise the impact.
I started on a more thorough coldfix last night and intend to continue with it today.
Thank you for your patience while I address my error, and I apologise I did not respond sooner.
ANOTHER EDIT (Tue 7th): Thanks to fantastic support from Mod Cel (Senior QA Analyst and unequivocably legendary human being) and Mod Helen (Lead Technical Content Developer, cheesecakestress and surrogate Easty), we released a hotfix about 5pm UK time that I (really, really) hope should prevent Death from assigning you raids bosses, while I'm working on (a) Monday (not necessarily this Monday)'s Reaper refactor.
If that partial fix does horrible things, I'm sure I can count on you to let me know. ;) If so, I shall weep openly and then fix it some more - not necessarily in that order.
YET ANOTHER EDIT (Thu 9th):
This morning, Mod Easty magiced a temporary Reaper's Choice interface until we can (hopefully, if it passes RC testing) fix the proper one on Monday. Also note above that Death was hotfixed on Tuesday to no longer assign raids bosses. More info here:
