This patch does not appear to be doing anything useful, and may hide errors. Currently, the save logic does not run through this path either so it did not do anything. Additionally, properly implement support for handling RegionFileSizeException in Moonrise.

Subject: [PATCH] Optimize Dynamic#get Missing Keys
|
|
|
|
get was calling toString() on every NBT object that was ever asked for an optional
|
|
key from the object to build a string for the error text.
|
|
|
|
When done on large NBT objects, this was using a ton of computation time building the
|
|
JSON representation of the NBT object.
|
|
|
|
Now we will just skip the value when 99.9999% of the time the text is never even printed.
