Sudden decrease in votes on apocalypticart@feddit.de after 0.19 upgrade

This is the chart of the votes for the latest posts on !apocalypticart@feddit.de.

This may be just a coincidence, but I find a bit weird that the votes went down to almost zero exactly when lemm.ee[^1] and feddit.de[^2] upgraded to v0.19.
