Subject: [PATCH] Handle Excessive Signs in Chunks creating too large of
|
|
packets
|
|
|
|
Also adds a limit to stop sending Sign data to client after 500
|
|
signs per chunk to limit client lag.
|
|
|
|
Use -DPaper.excessiveSignsLimit=500 to configure that limit, or -1
|
|
to disable the limit and let your players be abused.
