• Fixed a small memory leak in the new COTW tracker
• Potentially fixed a ConcurrentModificationException involving the TransientEntityTracker (report this error if you encounter it)
• Music discs removed from the default fishing_treasures.yml
• Optimized how mcMMO saves player data (should improve timings on servers with bad disk speeds and or bad connectivity to their SQL server instance)

NOTES:
No one likes fishing up music discs, if you want this change it is recommended you delete fishing_treasures.yml and let it regenerate

(You won't have this file if you haven't updated in a while, if so you don't need to do anything)

If any of you encounter a ConcurrentModificationException error that mentions TransientEntityTracker in its stack trace after this update let me know, I have another fix in mind for this if this update didn't fix it.
