Bard Chime Spawn Logic

Recently, I've noticed that Bard's chimes seem to like to spawn under enemy turrets and in their jungle early game, then switch to spawning in "safe" territory late game, when our team is pushing.

Is there something mixed up with the spawn logic? One would think it should be the other way, encouraging the player to roam and ward during lane phase, while late-game encouraging them to move between lanes if pushing. Maybe the chimes themselves need to be given a logic check that sees if a team's lanes are pushing, and then spawn them accordingly.

It's just frustrating that I have to take a squishy champ into turret range, or into a dark jungle deep in enemy territory to simply get chimes after about 5 minutes, and then have to abandon pushing lanes to go pick them up later.
