I occasionally lose the brushes which I've set to certain tags (such as "dry brushes", "distorts", etc.).

The tag group labels are there, but the brushes are no longer in them. This only seems to happen (or coincides with) when windows doesn't shut down properly (even if I've quit Krita before hand).

So there is no crash report but the effect is there.

Which file stores this data so I can at least restore the tag groups?
