Problem description

Set a repeatable quest. After completing the quest, wait for quest cooling time. After the cool down time is over, the quest progress still shows the completed progress, and the button to receive the reward is available (nothing happens after clicking)

Example

Create a quest that kills 5 zombies and rewards 1 diamond. The cooldown time is 10 seconds. Now the quest displays [kill zombies 0 / 5]. After killing 5 zombies, the quest displays [kill zombies 5 / 5], receive rewards, diamonds + 1, enter the cooling time of 10 seconds. After the cooldown time is over, the quest still displays [kill zombies 5 / 5], but if you kill five more zombies, you can also receive rewards and enter the next cycle. It's just a display problem. In a single player game, the [kill zombies 0 / 5] will display correctly after the cooldown. The problems described occur only on the server.
