I just discovered that this icon theme can cause gnome-shell ver. 3.28.4 in Ubuntu 18.04 to abruptly log out a user. This is very problematic as the user will lose their work. Your icon theme is aesthetically beautiful. Do you have a version that is compatible with GNOME Shell 3.28.4? The current version downloaded from gnome-looks.org is giving the issue.
