Clearing cache does not help, got to reinstall and import my wallpaper back and it starts to work again.
[edit]Seems that clearing data and import works. Can share the theme if needed.[/edit]
Reverts to some basic font, icon fonts (music player icon font mainly) just show a letter, icons show a questionmark. And the bitmaps just aren't there.
I got an external SD card and that's sort of made into internal memory by the phone. Not mounted as internal memory like you can do on android usually but think what Huawei has done is to just make SD card look as internal memory to programs (as with some file browsers when I choose to browse internal memory, it actually goes to the SD card).
Seems to work on APK ones. (tried one) The template I'm using was made by me from scratch, would love to be able to keep continue with it. I keep modifying it constantly. Today actually lost about a week's worth of edits due to forgetting to save before I cleared the date :(
You can roll back changes with the "roll back" icon also you should be able to fix the problem by opening the editor and saving again after the reboot. That said, if this does not happen on APK skins, it might be due to the fact that, for some reason, SD is not available when live wallpaper is started, i will try to reproduce this (and super sorry for the incovenience, its just quite complex to reproduce and it doesnt happen to everyone so it might be device specific)
I think something in the new version made the theme work for a while without clearing data. Might be that it was the update itself. If there's somrthing that your app does when it updates, you could make a button in some menu to repeat it or something. "fix me"... worked till my next restart
I am using only widgets and wallpapers that I created and I am having the exact same problem where all of my imported fonts have disappeared. I can add them back in but they're gone with each restart.
I have the same problem. I copied a bunch of fonticons into the Kustom Icons folder, and after reboot, these files have disappeared. Copied them back there, and again they've been deleted.
I'm not using SD card. S9+ with internal storage only, paid KWGT and Nova Launcher premium.
