Zyra keeps buffs FOREVER
I just played my first real game with the new map's updated jungling camps. I was playing Zyra, and I noticed after killing the enemy jungler there weren't any timers on my buffs that I had collected off of him. At first I brushed it off and accounted it to maybe me just not knowing the new spot for the timer.
However, a little later down the road I died to my enemy laner. No big deal, beyond that I was slightly miffed I had given them double buffs.. except, I spawned with them, and found that she did not have them. The entire game went like this for me. I kept asking my other team mates if the buffs transfer still .. but no one would answer me. I'm not sure if it was a graphical error on my end that made it appear like I had the buffs, or if I actually kept them all game.
Tl;dr: Buffs forever. Not sure if for real or if graphical error.
