Losing control on seedlings

[Melly]

Sometimes, and this tends to happen when I have a large number of seedlings, like 500-1000 and more, I lose control over some seedlings on my asteroids. I once had around 40 seedlings floating around an asteroid, with their number showing on the bar at the bottom, but I couldn't control them. The arrow to move them wouldn't even appear when I dragged from that asteroid. This seems to happen in smaller numbers as well.

Actually, nevermind them showing on the bottom, they don't show up there either, and it seems they don't react to enemy seedlings, effectively making them useless.

EDIT: It seems that, after some time, they'll move on their own to where I first told them to, and they become controllable again.

I've had a similar but different problem.

Sometimes an asteroid says it has 0 seedlings, but there's about 10 flying around it, and you can't control them... Weird...

Please, tell, on what level did it happen? Have you plant something on that asteroid?

It's usually the result of too fast seedlings orbiting around too small asteroid and trying to land, but always missing.
But I thought it was fixed in all places.
