i think i may have found an answer to the save problem. if you lost your save, try going to the menu in game and then refreshing. i did this and all my stuff came back!

theres a glitch where if u buy something, u lose it when equipping something else and u leave the game. i had the final doom ray, bought the magic spell core, left the game on it and when i came back, i had to buy the doom ray again, but my blops stayed at the same total they were at last
