Same with LAST.
Same with LAST.
Yo psylle,
One possibillity is that the players are unfrozen, but they didnt click on "attack" yet so they are in a state "between" - in that state they still appear as frozen on the teamoverlay
Other possibillity is that it is a bug. When you appear frozen in the Teamoverlay your player's head on the bottom of the screen (dont know name) also appears frozen. It collides in some way - and it collides also with the LAST sign.
not very helpfull but I tried....

So I guess you might looked wrong, or it's what Andi/Absynthe alraidy said; "the state between frozen and playing"
overlay give you the location of your teamates frozen or not and as far as i know it s always correct
if you see (hear) someone is frozen you just look on it and you see where he is and so you can go but yea i agree the frozen thing doesn t works good most of time you see frozen peeps while they are not etc ... dunno why but it s like this since ages

minky Told :
man overlay is the best thing ever, i use that to find frozen teammates all the time...sometimes its wrong with the frozen part but just look if they have health or not, dont look at their face whether its frozen or not cuz that is buggy, but if they have 0 / 0 they are dead and frozen that is never wrong

hail to the minky
Minky is very right! I could cry about people roving around the map and not finding the frozen bodies...!
Teamoverlay is one of the most important features in my opinion - As I am Thawmaster! 
wen i used 2 use osp in freeze, it used 2 show more than one person with the same name, with same score and same ping sometimes, but the team overlay was fine. In efreeze there is definately a glitch for the frozen players but one way 2 tell on overlay if they are frozen or not is the location. If some1 is moving and not frozen, location should change
go by the health...much ezier
depends of server config for that mad-jak (i think)
i agree with minky : health ---> best way to know
ciao WeedAssault
yes yes i know all :P
