I finished the quest and I can't exchange my scroll for xp.

Exit the game and click fix client in launcher updates tab. If it doesn;t work try to install patch manually - https://drive.google.com/file/d/1K43HqlteJos1mAA-YvbtTE_PCQjWTBcj/view?usp=sharing
or reinstall the game client - https://cerberus-games.com/threads/connect-to-cerberus.21688/

P.S. the quest from pvp npc vendor is also has 24h cooldown, You can;t complete same quests twice from 9am moscow to 8.59am moscow

But time has passed and I lost the letter. Will I run out of XP after doing the quest?
