We were attacking a level 3 base with about 4400 defense.. I had about 4k attack (plus 2 tetra seekers) I was doing between 35-45 damage per attack and I was the #2 attacker ... they activated the Remote Intrusion and I got notified that I was affected by the 90% debuff .. .. I continued attacking and the lowest attack I registered after being hit with that was about 27.. Now I am no math wizz .. but I am thinking that is not working the way it should. No debuff showed up on my ship stats either..

No the Remote Intrusion doesn't work properly, though I was under the impression that it was going to be fixed.

BTW, a while back I got whacked 3 times with a RI during a base attack, didn't do anything.
