Fenrus will not save uploaded icons

[pathwayx99]

I installed Fenrus in a docker image a couple of days ago (like what I see!) and proceeded to build my custom dashboard. I have a multi-user setup, so I created some system groups and some user groups and populated my dashboard. All good.

However, as of today (I fiddled a lot with new icons etc), any item I try to change/add with a custom icon (uploaded via the "browse" functionality) will not work. The icon is uploaded normally, I can save out of the item, but when I try to save the group it does nothing. The UI continues to appear responsive from that moment on (ie overlays etc work), but any clicks do nothing. I have to reload the page. If I do, either the new item doesn't exist, or if it was a change, the old icon remains.

Note this does not happen if I choose an icon from the built-in list.

The same happens to me.
Single-user setup, it happens anytime I add an icon and try to save Group.
This is the log coming from docker:
