I did put in a bug report and a tweet to jagexsupport but thougth a post here may save others some hassle too. Currently the items rewarding exo for skills are not working properly. The chat message tells you the esp you should have received but you dont actually get it.
The exception being fallen stars and lamps with specific skills, they work on some of the skills but not all. Thieving and magic work so far for me. spent 75 keys before I noticed this, don't do the same thing.
