While these logs indicate something is 'off', we've had no reports of visible 'issues' with entities, and no one is going to take the time to debug this farther, so just getting rid of the logs so it's like its never happening! Ignorance is bliss.

Subject: [PATCH] Add some Debug to Chunk Entity slices
|
|
|
|
If we detect unexpected state, log and try to recover
|
|
|
|
This should hopefully avoid duplicate entities ever being created
|
|
if the entity was to end up in 2 different chunk slices
