i've been trying to do the 3 star achievement killing advlt deathclaws with .22 pistol ( silenced .22 pistol ) and dynamite.

i've killed dozens with the name just showing as deathclaw...not young deathclaw, although it credited me for killing one called blind deathclaw.

after killing dozens of them with the name showing as just "deathclaw" the log shows me at 3/5..is there a specific place that it only counts from, as this is annoying ( spent several hours on a achievement that i thought i could do in a few min ).

any help would be appreciated
