Can't access some levelpacks

[kenakofer]

On Arch Linux, running an SDL build, I can't select "Change Map Set" from the main menu. Doing so crashes the game with this error on the terminal:
terminate called after throwing an instance of 'YAML::BadSubscript'
what(): operator[] call on a scalar
zsh: abort (core dumped) asciiportal -m extralevels
Some packs also fail to load with the -m flag: challengeme, evil, extralevels, GRVNG, ivanq, and Mechanist. They all have the same error as above. All the other packs seem to work as far as I know.

I can't reproduce using asciiportal 1.3-2 from https://www.archlinux.org/packages/community/x86_64/asciiportal/

Maybe the content of your YAML files in ~/.asciiportal/ is corrupted? Try to backup/remove this directory.
