No, so far no bugs worth mentioning. All works well, apart from more incoming updates than usually on a Debian System.
The problems I ran into were mostly with GNOME and Hotkeys for Apps in Wayland. Like Shift + F12 to open a Terminal does not work reliably when set in the Terminal app, but works well when set in the Gnome Settings as a global Shortcut. But I would file that under annoyance rather then a serious bug.
The system works that armor pieces usually have three spikes, but they are never in the same group (top three, lower three).
So to focus a similar distribution like you picked up, you would use a high recovery ghost mod to guarantee a spike in the top group and ideally force the remaining two spikes to the lower group of three.
