I made it through sever. here the task was added to the rest of you just check in the "_RefQuestRewardItems" in _SHARD database has rewards that task yet, I still remember the task was added in "_RefQuest" so that you should check in "_RefQuest" then added rewards in "_RefQuestRewardItems" while the media had their reward.
EXAMPLE: I want more reward for the task 5 nova = moon you find the name of the task before
then added "_RefQuestRewardItems".
