New command option when editing player datas (karma, tier, wanted): Do not send messages to the target player using the -s OR the --silent argument inside the command.
/karma edit player Rosstail tier set sheriff -s
New config options:
pvp.send-message-on-karma-change (DEF TRUE)
pvp.send-message-on-tier-change (DEF TRUE)
pvp.send-message-on-wanted-change (DEF TRUE)
Put these options to FALSE in order to not receive karma message on PvP.
FIXED
