Good afternoon,
Ok. While in your problems directory, can you please type "ls ../" and show us the output. You should see "zapdos-opt" as an output (below is an example).
(moose) corey@cdechant-ThinkPad-P51:~/projects_GEC2020/zapdos/problems$ ls ../
build GEC2020_inputfiles LICENSE problems scripts test zapdos-opt
crane include Makefile README.md squirrel tests
doc lib moose run_tests src unit

Thank you,
Corey DeChant
