I don't think he was turned on this weekend. 8000 sp on a weekend quest? seems way to low. don't see much of an increase and another quest only 6,050 I have NEVER seen him give this low sp

Alexander's sp prizes are never really high, not even during special weekends. Usually his item prizes are more valuable than for other quests. He is giving out extra books during the weekend, though not for every quest, and that seems to be working correctly today.
