Had to completely redownload League.
Earlier today approx~ 2 hours ago: I was in a match as Gragas Jungle and all of a sudden a wild pop up appeared, It said:
"An essential game asset was not found when loading the game:
TeemoMushroom
Please try reinstalling the game...... "
And some more crap about support. Please tell me why this happened and my hatred for Teemo has reignited even more.
