(disclaimer: addressing an issue, do not know the particular case)
Burns, you used a few pretty strong words but sidestep Rumi's issue :-(
It seems that most of 'topics that has been there before' exists only in memories of vets, not written down and as such pracically unavailaible for newer MDers. Essentially there is a lot of people apprearing mysterious and knowledgeable and using non-spoiler policy as a cover and refusing eny information on things/events past or game mechanics. Some of them may know something - some just know nothing but hints they drop escalate mess.
As a consequence it seems unavoidable that new people will do things that have been done before and differently. Graves? If nobody took some effort to commemorate things, events, people there are no graves to spit on. It seems the other way around - new people come with potential and energy and they are spitted in a face 'it's been done before and better, don't touch it. how? cannot tell you, try to figure it out yourself'. And they either try - or give up
Either you have everything written down and people move in packs along well marked paths of propriety - or people try to find these paths, often just getting them dead wrong.
About RP quests - I have no idea how they are managed. Is there some vet committee that accept every development? Or somebody accpepts concept rightfullness? Or is it all left to sponsor/ author?
