(CLIENT) -1010 IP?! / TP turned into Heal...

After I purchased at the store with IP (1350 IP cost), instead of having around 300 IP left, I got -1010 IP. Tried refreshing the client, but it was still there. Only after I tried to buy the cheapest thing I could find - a seal -, that it went away. I'm not sure if the amount I have now is correct, but oh well, it's okay. Also, wanted to comment that on my last game, I took and Grasp of the Undying in champion selection. After a couple seconds, my teammates were telling me to please take TP. I smiled and thought "they're probably premades trying to have fun, ok", but when I got to the loading screen, indeed I had and Fervor of Battle, which were the summoners and masteries I had the previous game. I didn't have time to take a screenshot of my champion selection, as I thought my teammates were trolling and thankfully, it didn't compromise my gameplay too much, but it could and overall, just a weird af bug...
