Weird Glaive bug?

does anyone get this too?

usually when im grinding at shaks and edimmu i use the following skills.

SSTruth
SSSoul
Ghost Spear Prince
Spirit crash
and Flying dragon fly....

so i start grinding.
then when i crit. i usually crit 3-4 crits in a row (12 83% crit ftw)
then so i crit truth, soul. but then Ghost spear gets a crit value. but doesnt say crit.

lol a weird bug :) and i was testing this out when i was p lvl ongs. it usually hits 6-7k then it hits 12-13k out of nowhere haha(and it doesnt say 'critical')

I've had that too xD Don't know why though

haha i thought i was godly for a second because i was p lvling at chakjis the first time i saw this. and i was telling my friend i was hitting 12k non crits lol. but yeah. i wonder why the crit isnt showing up but the value is..
