Missing resources

[HylianUsual]

Hi. I have Solarus v. 1.6.5 installed as a snap on Xubuntu 20.04 and I've just started a project. The "entities" folder is empty and I'm missing at least one sprite from "destructibles". Any help?

It is normal that the entities folder is empty: there are no custom entity scripts by default (but that might change in the future).
Which sprite is missing from destructibles?
