2 people had issues where some plugin is doing some reallly insane NMS hackery that created invalid worlds, which caused some errors... Really don't understand what in the world they did, but putting in a dumb guard that shouldn't even be necessary to just not send the sound effect rather than erroring.

Subject: [PATCH] Optimise entity hard collision checking
|
|
|
|
Very few entities actually hard collide, so store them in their own
|
|
entity slices and provide a special getEntites type call just for them.
|
|
This reduces entity collision checking impact (in my testing) by 25%
|
|
for crammed entities (shove 130 cows into an 8x6 area in one chunk).
|
|
Less crammed entities are likely to show significantly less benefit.
|
|
Effectively, this patch optimises crammed entity situations.
