There are only two problems up there right now and one still needs to be done. There is plenty of potential for more problems to go up.
The attic is a little difficult to find. Once you find the jungle boulders follow a little trail up the hill (north east) after a lot of scrambling you'll reach it. (bad description I know, sorry next time I got out there i'll look around for some better landmarks to get you there.)
