I was able to get to the upper tiers by completing the one before them. Example: once I beat 4, 5 showed up.
Can you please post a screenshot of the account where you only see tiers 3-5?
Paragon and can only see tier 1-4
Spoke to the game team:This is by design. When you unlock a next Tier Level it will remove some of the bottom end as only X number of quests can be displayed at once. "These Quests are repeatable, so there's no reason to complete lower difficulties unless the higher difficulties are too difficult for you, in which case you wouldn't be unlocking the higher difficulties and losing the lower ones."
Tbh... I'm super confused
