Encountered today for the first time, but boy, is that annoying.

First of all, I got quest "pick 8 star shards" but mysteriously, before I even gathered the things needed to do so, I had already one listed as "picked"
Buuut... when I picked remaining 7, I still have 7 in my inventory but need 8 for "Souřadnice kurzu Předchůdce" so I cannot really continue without it...

Would you be so kind as to resolve this issue? Thank you!
