We are developping the plugin named BigBrother which allows MCPC (Java) client to connect to a PMMP server. And we have some problem and need a hook on player specific chunk unloading. So, I wrote a patch makes Player#unloadChunk() method protected. But I can't create a pull-request to PMMP github repository. Please help us! Any comment is wellcome! Here is the my patch. https://github.com/pmmp/PocketMine-...alharvest:feature/make_unload_chunk_protected And this is the BigBrother plugin official repo. https://github.com/BigBrotherTeam/BigBrother
