It seems that I have played a custom map as some point (not sure how long ago or I would decompile the offending map to get my answer) but on-screen prompts seem to be completely disabled for me (e.g. press space to jump is not displaying).

Does anyone know how to re-enable them? I can't seem to figure out what they are called which is making finding the console command very difficult. Thanks.

You want "gameinstructor_enable 1"

Thank you.
