Hi! Rest assured that the treasure count has not been reset. I do understand your frustration as I had terrible luck on Jinchuriki Treasure 2, but the count has not been reset. Also, there has been reports that stated players getting their super kage pull before 900, while others stating them getting it after 1k. Although there is a general consensus and idea of the average of how many seals you need to pull to get a rare or super rare, these are not always true as I've seen players get a ninja like Sasuke [Susano'o] way before the supposed threshold.

Hope that helps!
