Masked Compression (Ultimate compression in one go)

[shazzla]

Hi !

I know its funny ,but this is the first time i try to use masked compression.
And i run into the following problem :

In ARC.GROUPS i defined the followings :
$bink
*.bik
*.bk2

$bin
*.exe
*.dll

$audio
*.wav

$misc
*.asset
*.dat

My chain : -mzstd/$bink=bpk/$bin=razor:8m/$misc=srep+lolz:d256m:mt2/$audio=tak

AFAIK it means zstd used to compress those files are not defined in ARC.GROUPS.
But in my case zsdt is NOT USED on remaining files,instead compressed using TAK! (those files are renamed BINK movies)
what is the problem ? I dont understand....
Any help will be appreciated!
Thanks in advance!

ATM im away from my rig....
