Had Hosefill attacked and taken then flexed. was under the impression that it stayed on my news feed for 2 days. not there

If someone stole and fluxed a planet then you won't be able to see it. That is unless you managed to alert it before he fluxed it.

And even then, you would only be able to see it for the 12 hours of the alert.

The event will show on your newsfeed for 2 days, but you'll only be able to click on the attacker: Hosefill
