Well, I played a quick FFA this morning - Random races, hard AI, 4 players - all players got Advent.

A funny game, until I noticed something odd: A enemy guardian was roaming around in combat - with 4000 shield points. I guessed it was a display bug, but a few minutes later when I charged at the enemies main fleet, I suddenly saw this:

(For those who don't want to click: An enemy pPogenitor cap with 358877/2472 shield points - thats 14586%)

I have no idea how it happened exactly - but there must be some sort of bug with Advent vs. Advent abilities.
I attacked the Cap and brought it down to about 30% hull, when suddenly all fire from my ships started to charge the enemies shields! After a few strafing runs, I finally noticed ("Why isn't that cap down ye... holy wth?!") - I waited for some time for all abilities to wear off, but the shields didnt't decrease to 100%...

There were some guardians on both sides around, I had Malice, Vertigo, Shield recharge and  Vengance on autocast, but did not notice what combination triggered the bug. And with my luck, I probably wont even be able to check the replay...

Anyone else has seen this?
