leve xp help

Could someone help me figure this out?

I was getting 11k xp yesterday from a level 30 leve in tranquil. the one where you gather the turtle eggs. Its awesome because you can do it in like 30 seconds over and over again.

Anyway today when I logged in, I was only getting 5.5k xp.

So what was causing the double bonus yesterday? I do have rest xp from logging out in a sanctuary, but afaik that's just bonus for killing mobs.

Is there some new bonus for leves somehow? Thanks!

EDIT: I figured it out - after I started my leve, I unequipped my soulstone. X_X who knew.
