Fonts don't generate on large assets

[Drackrath]

I have a list of over 500 Assets generated by FLR

My Fontss are defined like this:

fonts:
  - family: FuturaCyrillic
    fonts:
    - asset: assets/fonts/FuturaCyrillicBold.ttf
      weight: 700
    - asset: assets/fonts/FuturaCyrillicHeavy.ttf
      weight: 800
    - asset: assets/fonts/FuturaCyrillicExtraBold.ttf
      weight: 900
    - asset: assets/fonts/FuturaCyrillicMedium.ttf
      style: normal
    - asset: assets/fonts/FuturaCyrillicBook.ttf
    - asset: assets/fonts/FuturaCyrillicLight.ttf
    - asset: assets/fonts/FuturaCyrillicDemi.ttf
  - family: Avignon
    fonts:
    - asset: assets/fonts/Avignon.ttf

Though they get deleted on generation.

Possible Solution:
Flag the FLR wether it should generate assets or fonts.
