Subject: [PATCH] MC-4: Fix item position desync
|
|
|
|
This fixes item position desync (MC-4) by running the item coordinates
|
|
through the encode/decode methods of the packet that causes the precision
|
|
loss, which forces the server to lose the same precision as the client
|
|
keeping them in sync.
