Issue Description:

Players randomly can't join the server until (sometimes) a restart of the server resolves it.

What happens:

Player tries to join, but gets "disconnected". The server's debug log reports blood magic's spectral tiles to be related to the issue.

What you expected to happen:

Player can join server.

Steps to reproduce:

  1. Attempt to join server nearby someone who is playing with Blood Magic stuff
  2. Get disconnected, with "can't place player" error on the server-side log

Affected Versions (Do not use "latest"):
