Call me dumb! But didn't you used to be notified of the players that are invading your planets? So why are we not alerted to the player now? If this was an update I was not notified and I detest this new update if so.
Scenario --Nobody tried taking your planet, Nobody failed but will be back later-- Can't defend a planet against nobody, whats to stop them from continuing? Unless they take the planet. Then that just adds a new world of hurt.

They have to use an artifact, set off a trap, use a Sab ability or have a successful invasion for you to get an alert.

Okay, Thanks Darth.

so trap ur planets, if they decide to come back, successful invade or not, they get caught

You get told at the first attack that PlanetX is under attack! It doesn't tell you WHO is attacking which was what PS was asking. It's always been that way.

Thanks Liberi, It never fails....but I am not dumb it used to tell me, but I guess like Darth was saying the planets must have been trapped or artifact used on them.

If you have found the planet flux - tracer in the CTL you can use it to at least find out who has scanned your planet and then try to find them in the BT.
Would be nice to have an artifact that gave you a direct link to them if they had attacked. Kinda like a reverse wormhole emitter, guard the planet in question, warp them back to the planet, commence the smack down.
