My quest tiers have been reset twice now. When it happened at tier 2, I didn't realize it and just did quest after quest being sent to trader after trader before I realized I was doing only tier 2 quests and was never sent out of the snow biome. I had to manually leave the snow biome, find the desert biome and then I would start getting tier 3 quests. I was eventually sent to the burnt forest for tier 4 quests. After a couple of tier 4 quests I was given tier 1 quests instead. Has this happened to anyone else?
