Your LimeSurvey version: 3.28.66
Own server or LimeSurvey hosting: own
Survey theme/template: custom extension of vanilla theme
==================

I was managing assets. Then I clicked admin button: Clear Now. (inside General Configuration in Admin web interface).
I supposed old assets cache were deleted then recreated on demand but Leaflet.* assets are missing.

Which action triggers survey's assets re creation?

Do i need to rebuild the asset directory by hand, putting requested files?
