Mundo Unresponsive

Just got out of a game where I was playing Mundo (pool party skin if it's of any consequence) and the champion ignored most of my commands for movement and abilities.

I didn't lag, I held a steady ping of 25-30 ms, my internet connection is fine, and I was able to chat without delay. Mundo, however, would randomly freeze in place or move after a delay. I once spammed the flash button to get him out of a bad fight and he wouldn't flash. Another instance occurred in which it took him several seconds before initiating recall despite me clicking on the icon for him to recall.

I eventually just stopped playing because the match was absolutely unplayable for me even after attempting to disconnect from and reconnect to the match.

This wasn't the first time I played him and noticed a delay in his response time to commands. But it wasn't this bad in the other match I played with him and so I thought it was just a little lag on my end. But this definitely isn't lag. The game is playing in real time and I was made helpless to watch my own champion die over and over again all because of a game breaking bug.

So, now I know not to play Mundo until this issue is addressed and fixed.
