Runeshards zeroed out?!?

After a lengthy play session I logged off to grab some food. Came back and I had 0 runeshards. I had around 2.6k runeshards prior to logging off. WTF? There is no way I played through 2.6k runeshards in a few hours. Plus I wouldn’t have ended up with exactly 0 because it takes 3 per run and I have 20k+ of every other material

I am having the same problem. Lost all my runeshards. I was running Pits fine yesterday and had thousands of runeshards. Now I have 0 runeshards on my only Seasonal character. Fortunately, my Eternal character still has over 8000+ runeshards. With 0 runeshards, means I would have to start collecting them again to run Pits on my seasonal character.
