Maybe I am reading or hearing it wrong from multiple people but after the server wipe about a hour into the game I got lucky and found some kevlar pants blueprints. After that I studied the plans, farmed some more resources and logged out.
My house got raided ( oke well shit happens ) I logged back in and found a new place. Put down my new sleeping bag and started gathering some more stuff. Died again because of a zombie and respawned back at my sleeping bag and then died again because I tried to get my stuff back when the zombie was still nearby. I then tried to respawn again at the sleeping bag and it said I had no valid repawn point. I then suicided a couple of times and after a while I could get back to my sleeping bag (I don’t know if this is a bug or a respawn protection feature)
Later on I finally managed to gather some more resources and thought oh yeah I have the kevlar pants recipe, I scrolled through my crafting menu : No Kevlar pants.
I always thought studied recipes where permanent. Anyways it doesn’t really matter its still a alpha but just curious if this has ever happened to anyone else or if this is normal.
