Last night I powered up a level 51 diamond Poltergust with another level 32 shiny gold Poltergust and the diamond variant went up to level 58, almost 59. Everything was fine, I was even playing with it for a while until at one point I quit the game, I came back to open it and I saw that they returned me to level 51 and without being shiny, I thought "If they returned it as it was then they should have returned my Gold Squigly" but neither was my Poltergust shiny and it was very frustrating.
