Why do we lose the XP overflow? Example: I lack 1.75Q to reach the next level. I kill the baddie, who is supposed to award 3Q, but I start the new level with 0 XP. What happened to my other 1.25Q?
Missing soul shards ... I had 125 before killing off some red mud blobs, they doled out a bunch of them. After the mission ended, still has 125 shards.
Try an export / hard reset / import. It should restore the missing UI. Let us know if it doesn't!
