Setting refbox related environment variables does not affect the game

[kousheekc]

I tried setting the following env variables in my local_setup.sh but it did not have an effect on the game as visible in the picture.

export REFBOX_CONFIG_CHALLENGE=./../config/refbox/challenges/prod/c0.yaml
export REFBOX_CONFIG_MPS=./../config/refbox/mps/mockup_mps.yaml

I initially thought that the paths were wrong, so I added the full paths but that did not work as well.
