Subject: [PATCH] Ensure Entity is never double registered
|
|
|
|
If something calls register twice, and the world is ticking, it could be
|
|
enqueued to add twice.
|
|
|
|
Vs behavior of non ticking of just overwriting state.
|
|
|
|
We will now simply log a warning when this happens instead of crashing the server.
