I am testing the project on my MacBook Pro using Docker and I noticed that I got some warnings after any mission that displays the ASCII treasure chest such as mission 3 or mission 9.

Docker information

$ docker images
REPOSITORY   TAG       IMAGE ID       CREATED       SIZE
gsh          latest    99a316e90dd2   7 hours ago   232MB

Console output

[mission 3] $ cd
[mission 3] $ cd Castle/Main_building/Throne_room/
[mission 3] $ gsh check

Congratulations, mission 3 has been successfully completed!
