FYI,

Critical Queen takes no damage after a direct hit from a properly stacked payload of Chaos and Gemini missiles from a Ragnarok 3, in perfect line of fire.

Behind me came a Guardian firing at me, in front of me an Assault, and to the side an Overseers. So I released InfiniTurbo, turned left, and hid behind an asteroid. ThenI heard the missile payload impact the Critical Queen, but it took no damage.

This has happened to me before, only now did I figure out the possible cause: if the Critical Queen loses sight of me before the missiles hit, it takes no damage.

Thanks.

Do you have a date / time / game-location? We need to look at sector logs to understand what happened.

was today may 11, Odia, ~ 1300 .. 1400 game time

Don't worry, i want FYI, Next time I'll take the data.

Time ago i hit three times a Critical Queen with full stacks of missiles after reloading in Trident and the three times the Critical Queen take no damage (dont remember when, where, or if sector having lot asteroids)

if you do /time and then take a screenshot, you can refer back to that to get the location (listed on your HUD) and time (it'll list GMT, but that's fine, just specify here).

was today may 11, Odia, ~ 1300 .. 1400 game time

We tried to examine the logs, but we don't know which attacks to investigate over such a long time period.

It appears that you did successfully kill Queens during that period, so it's not like you weren't able to damage them at all.

If it should happen again, perhaps do what Luxen suggests and capture the exact time in a screenshot?
