You still only get 1 50 pt coin but you should have gotten 2 20 pt tokens (or one 15 pt and 1 20 pt if you took longer than I think 5 minutes?) as well. Looking at your logs you got a 50 pt, a 20 pt, and a 15pt along with 18189 sP.

On the 23rd, the recycle beast was accepting 1 point wizard tokens and so a bunch of people were removing tokens 1 at a time and that was creating a huge amount of lag. It shouldn't be that bad again.

Does this take care of everything for you?
