Global variable not sticking

[noingwhat]

void loop() {
  gcode();
  runPlanner();
  extern void loopingColorSearch();
}

That last line is interesting. What do you think the net affect is?

Ohhhhhhh, that's probably the issue! I was just playing around with the code and tried that out but I could see why that could cause the bug.

I'll fix that and test it out when I get home, thank you!
