Ravenloft Revelations was made by seraphimsage I think, who also did the Nihil Triology. He retracted his work from the vault at some point of time and I doubt he is still around somewhere. It is quite a pity because the Ravenloft campaign is actually fairly good (a lot of spelling mistakes, companions do not level up properly) but you can take a lot of meaningful decisions and there are some very cool items and plot twists. At some point of time he only gave away copies when you asked him via mail, I got one, but that must have been some ten years ago. I did not play it at this point of time because it was still full of bugs, but I replayed but besides the issues mentioned above I had a smooth playthrough and a lot of fun for about five hours this afternoon, taking the provided sun elf necromancer to level 12. You can clearly see where the area design was redone at some point and where it wasn’t. It still has a certain appeal, a very rustic one though in some areas, such as the garden or the waterfall of sorrows.
Be aware that topics such as suicide and child murder make an appearance.
If you want a bugfix/patch I would assume you have to make it yourself (such as the fanpatch for White Plume Mountain).
Hope this was still helpful.
PS: Anyone knows how the dryad in the garden is relevant?
