[retrooper]

Can you please give me more information by following the format. Server brand (including server version) and plugins so I know what I need to reproduce.

[retrooper]

Related to any other issue?

[MWHunter]

it's broken on 1.8 and 1.18 servers. Not related to any server brand. Via* is being used for 1.7 support.

[retrooper]

1.7 players work for me.

[retrooper]

Assume its a chunk packet issue?

[retrooper]

i think the title need to be a bit more precise. Just looking at "1.7 players are broken" makes me think they cannot even log in or so.

[Tofaa2]

Can you please give me more information by following the format. Server brand (including server version) and plugins so I know what I need to reproduce.

in 1.8 players dont really work properly. Same with my issue where it returns null

[MWHunter]

i think the title need to be a bit more precise. Just looking at "1.7 players are broken" makes me think they cannot even log in or so.

I still can't log in with a 1.7 player. Enable the debug listener and you won't be able to log in either. Might need protocollib too
