thank all

[janiii]

do you have some other game client versions (MinClientVersion, MaxClientVersion) enabled than the latest?

[dip_bow]

yes janiii.

[janiii]

yes janiii.

so, that is the problem. you enabled other client versions and that clients are sending other packet structure than server is expecting.
if you enable other version of client, you have to expect packet problems.

[dip_bow]

thanks for the help, I've resolved the doubt
