[GAMEPLAY] Ezreal ult visual bug

When ulting and killing a buff camp as Ezreal without vision of it, the icon remains on the minimap even after scouting it. I have had this happen at both blue buff and dragon.

1. Have enemy lower health of a buff camp to below current ult damage.
2. Hit buff camp with ult without vision.
3. Walk to buff camp to see it gone, then walk away and the icon will remain.

I've done this twice in ranked and once in the linked custom game so build does not appear to matter.
