As I didn't see any changes to Adventuring XP in the update announcements, I'm going off of the assumption that this is not intended.
Description of Bug Experienced:
After turning in quests, my adventuring XP surpassed 100k, and was showing fine as usual. But then, after a tick, it acted as if it only had 100k and was taken down to 99950 (in a tavern).
Steps to reproduce the Bug:
Acquire over 100k adventuring XP, then wait for at tick.
Expected Result:
AXP ticks down as normal, from your accumulated pool.
Actual Result:
AXP ticks down as if you only had 100k, regardless of how much more you have.
