OnPCLoadMapEvent runs multiple times

[Jethro]

OnPCLoadMapEvent:
    getmapxy @map$,@x,@y,0;
    if(@map$ == "guild_vs1") {
        announce strcharinfo(0) +" has entered GvG 1",bc_all,0x9B30FF;
    }

end;

Result:

Player1 has entered GvG 1
Player1 has entered GvG 1
Player1 has entered GvG 1
Player1 has entered GvG 1
Player1 has entered GvG 1
Player1 has entered GvG 1
Player1 has entered GvG 1
Player1 has entered GvG 1
Player1 has entered GvG 1
Player1 has entered GvG 1
Player1 has entered GvG 1

 

yup, it announce 11 times.

answered my own question, it was the duplicate causing the repeat
