Oldish bug, incorrect display of IP amount

This is a bug I've had for several patches now which I didn't bother to report because perhaps it might get fixed but nope.

When you start the client it shows the correct amount of IP but after you play a game it gets clunky. It shows that I have more IP than I actually do, the system, of course, does not actually think I have more, so it's a visual bug, but it's still a tad annoying to think you actually have 6300 to buy a new champ only for the system to tell you ''not enough IP''. The amount isn't much, it's about 200 IP off. It gets fixed by closing and starting the client but after a game it gets funny again.
