Henry's Tree- Level Restriction

OMG this was so so so shocking for me , don't know about others but for me . Today , i finished my quests and saw my friend list to see who is online . I do not know why but i clicked Henry's player card and clicked the tree  house button , what happened next ? It said 'You must be level 34 to visit Henry's Tree House today'.Hmmmmm what it means by today ? Ugh I really don't know .
