"insufficient IP" and "slow sound" bug

#1. This has been happening constantly of late...I will hit, say, 1800 LP, go to the store to buy a random champion shard, and be told that I have insufficient IP. Then, if I re-log, I will have less ip (say, 1625).

#2. After playing for an hour or two, I'll start a new game to find that the champ select audio has slowed down to about 1/4 of its normal speed, with strange static effects. It doesn't last into the actual game. This has been happening pretty consistently and requires a re-log to fix.
