So I was going through Nephalem Rifts to farm death breaths and ended up accumulating a lot of bonus xp from pools of reflection. From paragon 644 to 645 i ended up getting over 7,000,000,000 bonus xp which would be 9-11 pools of reflection. After collecting another I checked my bonus xp and it didn't seem like it went up that much (no where near the 10% of my required xp that it should). I wanted to check to see if it capped out, which I now learned it caps at the amount of xp you need to level up, but when i found another pool of reflection and went to check my amount of bonus xp, experience bar was blue an my bonus xp was completely gone. I collected that bonus pool and I then had a little of 700,000 bonus xp, which would be the 10% f my level.
So does anyone know what happened? Is there a reason it went away, like I broke the cap or something? Or did it just glitch and cheat me out of all of my xp?
