So we are now having in-game advertisement for the U49 gift redeem code. After opening the box, it gives me a bunch of various crown scrolls and a few mimic stones, which are UNSTACKABLE with the same other items I got from daily log in, GP reward, rare compensation cases, event boxes, etc. across many years, most of which I almost never use therefore ending up stocked piled in my home chest.
Why can't them be stacked? Is it intentional? If so what's the purpose for this?
