So, yesterday, I obtained a level 70 Tentacool, which is high, for the point in the game that I'm at, and, after some training, it evolved after an expedition completion. The evolution animation happened in the screen of experience of the expedition I beat. After that, it said the Tentacruel had around 3k HP. (Had 1.5k as a Tentacool). But when I ended the end screen of the level and went back to base camp it just said 1.5k hp and the original attack stat it had as a Tentacool. What went wrong? Why did it first say the evolved Tentacruel stats but now it says I have a Tentacruel with Tentacool stats?
