At first I thought it was something regarding my level being too high while the enemies' too low (I'm at level 34, which is not that high anyway..) but even going against enemies of the same level as mine, the result is the same.
Weirder thing: I was exploring a certain shelter (no spoiler) and I got ambushed by a dozen of synths.. and after they saw me, here they are, hiding like they're scared to death.. synths.
I hope it's just a bug and it's easy to fix, if so please help me, it's really annoying to fight someone that.. well, doesn't even try.
Thanks in advance, apologies for the bad english
