Using Tilix 1.9.6 on an Arch Linux setup. Not really really sure if this is a bug or not: Tilix has pretty much been my go to terminal more or less since it ceased being called Terminix and one of my favourite things about it is the Bookmark feature that I use extensively.
I've just done a clean OS install and from a .txt backup that I made, I painstakingly manually restored all my bookmarks. For some weird reason, after a restart (being a rolling distro, so quite often) poof, all of my bookmarks disappear. This has never happened before so would be interesting to hear any comments.
Thank you, much appreciated.
A small edit: Just to be clear I'm using the version from the Arch repository extra /tilix 1.9.6-5' The only thing that I've done differently is I'm using 'gruvbox-tilix-git' (Gruvbox theme for Tilix)
