Perhaps all invaded planets should be exempted from this update? That way the update won't provide immunity to those who invades before just before the update

This rank 20 thing allowed a rank 2 player to steal my best research planet fully developed with maximum level research devices that he cannot obtain for at least 10-15 ranks. Now I cannot take it back. You want my opinion? This was poorly thought out and implemented.

Are players still not putting any defenses on their planets?

From my experience, lower rank players tend to overdo the defenses till production <10 points per hour. Seems like higher rank players put more emphasis on production instead.

Well, I am sure there's a way to track recently invaded planets (48 hrs) but perhaps this task would be tedious

EDIT: Sure -> I think

That *might* work, but not in all situations...

Keep in mind as well that you penalize prohibitively on the cost scale for each planet detected in a scan, so now that I can no longer get my prime research planet back, I can also not afford to find new ones till I can afford the space for multiple larger scanning devices. OH LOOK, the newest planet I discovered belongs to a rank 4 player. You can see how this is becoming increasingly annoying, to the point this may become a make or break issue. The idea suggested that I was somehow at fault for not putting sufficient defenses on the planet was cute. Planetary defenses are just not up to the scale of ship offensive weapons. I had parked my ship in orbit, as this new player seemed to determined to take it from me. He had once already and I payed the prohibitive 250,000 credits to take it back. Then I was attacked by someone else on another planet. So I moved my ship to attack that person. And you know what that is when he took it the second time. SO, if I end up with a scan page full of planets I cannot attack, I assure you this game will quickly spiral into the not worth playing column.

Actually if you added this into the intro explanation that you get when you first start, this might work well. Something like: "If you are big enough to invade, realize that you open yourself up to invasions before level 20"
