1) 0.5.12a
2) win 10
3) conflicting traits
4) no real way to replicate as its up to rng to cause randomly generated characters with 2 or more traits that conflict with one another
5) while not major it could cause some issues. a slave i obtained from the random event where a tresspasser was found ended up having both "Mute" (cant work at occupation requiring speech) and "Pretty voice" (vocal occupations more effective)
