NEAT can't solve XOR completely

I’m currently implementing the NEAT algorithm. But problems occur when testing it with problems which don’t have a linear solution(for example xor). My xor only produces 3 correct outputs once at a time:

1, 0 -> 0.99
0, 0 -> 0
1, 1 -> 0
0, 1 -> 0

My genome class works fine, so I guess that the problem occurs on breeding or that my config is wrong.

Config

const size_t population_size = 150;
const size_t inputs = 3 (2 inputs + bias);
const size_t outputs = 1;
double compatibility_threshold = 3;
double steps = 0.01;
double perturb_weight = 0.9;
double mutate_connection = 0.05;
double mutate_node = 0.03;
double mutate_weights = 0.8;
double mutate_disable = 0.1;
double mutate_enable = 0.2;
double c_excess = 1;
double c_disjoint = 1;
double c_weight = 0.4;
double crossover_chance = 0.75;

Does anyone has an idea what the problem might be? I proof read my code multiple times, but wasnt able the figure it out.
