I built a chicken for the first time in ages last night and found it brutally unable to get past the engineers that surrounded it as it was built. Just a bizarre experience to see T1 engineers bully a chicken and then the chicken unable to find a path around T1 pgens nearby. 0 out of 10, horrible experience, would not recommend.
Seriously though, I'd guess you all know about this and it's being fixed in the next patch?
