I experienced 2 bugs until today after months. I collected all items for quest i clicked soul and the same time i accidentally i clicked case bag for another quest so i can't close the item menu for quest. im stucked so i need to quit again no save and i have to collect all items again. After that i logined again this time i completed i waited to full soul's heart, he didin't response i couldn't move my character. Then i couldn't save cuz it had bug again. It was so annoying situation.
