https://github.com/discourse/discourse/commit/75f37ac16a0277c1f6830b2140106a79e9afe310
Causes Discourse to crash (i.e. to show the server-exception failover) if updated via /admin/upgrade, with the following error:
ActionView::Template::Error (Error: File to import not found or unreadable: /var/www/discourse/plugins/lazyYT/assets/stylesheets/lazyYT.
on line 1 of theme_2.scss
>> ation/mixins"; @import "theme_variables"; @import "lazyYT";
------------------------------------------^
)
/var/www/discourse/lib/stylesheet/manager.rb:175:in `rescue in compile'
The error resolves when the update completes.
