   - I set it explicitly for Maven and Ant just now (and cleared all XMLUI caches) but the issue is still there
   - I asked them if they are building on macOS or Linux, and which Node.js version (I'm using 10.20.1, which is the current LTS branch).

+- I researched a bit more about the  issue with glypicons and realized it's due to [a bug in libsass](https://github.com/twbs/bootstrap-sass/issues/919)
+  - I have Ruby sass version 3.4.25 installed in my local environment, but DSpace Mirage 2 is supposed to build with 3.3.14
+  - Downgrading the version fixes it, though I wonder: why did I not have this issue on the `6.x-dev` branch before Atmire's pull request, and also on `5_x-prod` where I've been building for a few months here...
+- I deployed the latest `5_x-prod` branch on CGSpace (linode18), ran all updates, and rebooted the server
+  - This includes the "COVID19" ILRI subject, the new CCAFS Phase II project tags, and the changes to an ILRI author name
+  - After restarting the server I had to restart Tomcat three times before all Solr statistics cores loaded properly.
+  - After that I started a full Discovery reindexing to pick up some author changes I made last week:

+$ time chrt -i 0 ionice -c2 -n7 nice -n19 dspace index-discovery -b
