Message from the Developer:
The last update was more than a year ago, and I am sorry about that. I haven't forgotten about this project, or my any others, I just haven't found the motivation to work on them.
Now, what's next for this plugin?
I'm going to rewrite it from zero. The code will be much cleaner, and there will be support for multiple quests; a long asked feature, the stored data won't be so derpy, and a better API.
I am planning to release more frequent updates after the rewrite.
