Only top half of champions showing on map after making store purchase.

This weekend, I've seen this happen about 4-5 times on the regular Summoner's Rift map - I should note that it was during the URF games though. Pretty consistently, I have noticed that about midway through the game, when I respawn from a death or recall, return to the shop, and make a purchase, I have been finding that my champion has been stuck halfway above the map and half-way below the map. So it looks like my Poppy, Malz, Trundle, etc., are submerged and/or swimming through a grassy sea.

Suspecting that this might be the resurgence of an old bug.
