Hmmm really? I never noticed crows on steam live (98) needing two shots with the wrench and scarier face.
EDIT: Totally forgot to say which version I was playing prior to NTT. But yeah, 98 never gave me that problem.
EDIT2: Just tried to replicate the 2_hits_needed on live and couldn't do it. Every crow would die in one hit from scarier face...
