I was coding and when I implemented the findExtremum() command, debug log and print stopped working altogether, despite working previously. I’m completely puzzled, I restarted unity, commented huge chunk of code, spammed them everywhere to see if it wasn’t something that break at some point. It’s just mysterious …
I’m using unity 2018.1.0b13 with script inspector 3

Vector3[] vertlist;
Vector3 centroid;

minY,maxY,
minZ,maxZ;

vertlist = new Vector3[100];
discard = new ArrayList();
this.SupportVert = new List<Vector3>();
for(int i =0; i<vertlist.Length;i++){
vertlist[i] = Random.insideUnitSphere;
this.SupportVert.Add( vertlist[i]);
print (vertlist[i]);}
Debug.Log("loop");

print(minX);

//Debug.Break()
}
void findSupportVert () {
//compute centroid position
foreach (Vector3 v in vertlist){this.centroid += v;}
this.centroid /= vertlist.Length;
//initialize loop
Vector3 support = new Vector3();
float max = float.Epsilon;
//iterate points to get the support point
foreach (Vector3 v in vertlist){
Vector3 normalDirection =(v - this.centroid).normalized;//vector= end - start
//check all other points to find support
max = float.Epsilon;
foreach (Vector3 t in this.SupportVert){
Vector3 compared= t - this.centroid;
float dot = Vector3.Dot (compared,normalDirection);

//after iteration, if current is not support, discard
