Observed behaviour

I had just removed the Arcane Wall in a Ancient Vault using a Vault key. My Apprentice was following just behind me. When I used a sword to break the tripwire inside, the server crashed.

Expected behaviour

I expected to access Ancient Vaults without crashing with a Apprentice.

Steps to reproduce

1. Join a Server
2. Gain a Apprentice
3. With Apprentice following, remove a Arcane Wall in a Ancient Vault
4. Use a sword to break the tripwire.
