Bug - Issues with Anivia's Flash Frost and Frostbite - Gameplay

While playing as Anivia recently, there were multiple instances where her Q-Flash frost would be cast, but it wouldn't show a projectile, cause damage, or stun. It would go straight to cooldown instead of offering a chance to recast it to Detonate it. I am unsure if it can be recreated as it would seem almost random in it's occurrences, but it may have to do with the new terrain of summoner's rift. A second bug, though just an issue of clarity, is that the projectile will be hidden beneath Nocturne's Duskbringer's trail. Steps to Recreate: 1: Have an Anivia and a Nocturne. 2: Have Nocturne cast Duskbringer near Anivia. 3: Have Anivia cast Flash Frost towards the trail left by Duskbringer. 4: Profit Lastly, there is an issue with Anivia's Frostbite. When cast on an opponent running into the Fog of War and turning across terrain, Frostbite will land where the enemy champion was last seen and deal no damage. Steps to Recreate: 1: Have an Anivia and any opposing champion. 2: Go to the top right quarter of the jungle 3: Have the opposing champion run the jungle path along the Red Team's bottom lane Inner tower. 4: Have anivia cast Frostbite on the target as the enemy champion turns the bend leading towards the Wolf Camp 5: Profit

And as a side note, i just want to give my thanks to the People working hard to make the best game i've ever played. Keep up the good work fellows!
