(Steam version, but the issue is likely present in all versions)

The Memory Vault containing "Protect the Queen" seems to be facing an existential crisis. If a player smacks it without fully breaking it open, the Memory Vault can run off the platform's edge into the watery depths. Because it does "die" from fall, the Vault cracks open and the player can view the memory. However, it does not register as being opened in the journal and the memory can't be viewed again.

I didn't revert my save to try and get it again, but my inner completionist is crying. I want that 100% Steam badge :(
