bug on cooldowns display

This bug happens to me almost in every game, especially when I play support. The cooldown of the targon stacks or others indicators (potions for example) doesn't appear, like the buff is gonna last for ever. It is such a pain as I can't know if I'm getting a stack of targon very soon, if my potion is enough to save me after a trade etc.
Thanks for fixing this very quickly [slayer-jinx-wink]
