Paper/patches/server/0283-Mob-Spawner-API-Enhancements.patch
Spottedleaf da9d110d5b Remove chunk save reattempt patch 
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.
