Discoveries are "rediscovered" after loading a save where those discoveries where already present

This is happening because the the save doesn't store which "new discovery" messages have already been shown on the loaded world. So it will display those messages again if the discovery is "discovered" on a new place where the discovery wasn't present before. Nevertheless, the save file did not lose any information about discoveries already made other than the messages themselves. So technically there's nothing wrong with the load process.
