When a downloaded world template shows “Update,” pressing it changes the button to “Download.” After pressing “Download,” the update does not install and the button immediately reverts back to “Update.”
This issue is currently occurring with the Relics of the Privateers world template. The same behavior previously occurred with a different world template, suggesting the issue is not isolated to a single template.
The issue has been occurring for an extended period of time.
This template was originally downloaded a long time ago, and the issue began after a recent update became available.
