Hello all!
Let me explain this situation with Chronos Quests in more details:
1. We have several different sets of Quests for players on different Levels.
Some of the Quests in these sets can't be completed by players because of different factors. For example, player can't complete quest on Research/Upgrade agreement as he already upgraded all of them. Now, this factor is taken into account and when player receives set that contain Quests he/she can't complete, these Quests won't be displayed in the list of Quests.
Taking into account it would be harder to complete Weekly and Monthly Quests in this case, devs decreased the number of Quests you need to complete to get reward for them.
2. If you received Quest on Dominion Status activation, but you already have it activated, you just need to apply one more activator (no matter for how long it will be). You will prolong your Dominion Status and complete Quest in this way.
3. You don't receive one and the same set of Quests for several days. There are still sets where you will receive 5 Daily Quests that will allow you to complete Weekly and Monthly Quests.
4. In the very near future, devs plan to add new Daily Quests that will help you to complete Weekly and Monthly Quests easier ;)
