Blueprints wiping shortly after being learned

While scrolling Reddit shortly after wipe I found a post where a number of players experienced an issue with blueprints being reverted shortly after they were learned.

There have now been a couple of instances on [AU] Survival where players have remarked that their blueprints are being wiped after a few hours of playing. I believe this may be linked to the issue discussed on Reddit. Unfortunately these players leave the server shortly afterwards so finding out more details is problematic.
