We all know that, already did Ix'mnk w/ 3 organs pop where it was supposed to be "100%", nothing dropped, and GM expressly told that nothing was 100%. Hence the " ".
You still call these 100% drop unless you wanna be a smart *** and annoys people remembering them that "nothing is 100%". Someone asks you about a such drop, you'll answer "np it's a 100% drop" and not "goodluck man, it's a 99.6% drop".
And I highly doubt a GM will give them back a pop item, they messed up, having everyone in an alliance owning a rare/ex item = no drop, that's not a bug or anything.
