UNTAINTED PARADISE - NO XP

I just ran a fully juiced T16 waystone with XP bonus, and all towers around it giving xp bonus on Untainted Paradise that was supposed to give more than 450% xp. The monsters gave no experience. Zero. Outside of that, the XP in game also showed about half as much XP modifier as the bonus when hovered on the world map, which I would have welcomed instead of the fat zero given. Please fix this - it's super frustrating.
