Yeah thanks that looks right from reading the updater plugin again, I'll update the AFK Manager with that fix thanks.
I have never seen that Suicide error though, not sure how that happened, let me know if it happens again.
EDIT:
I actually cannot replicate that error at all when I try to compile using the regular updater.inc and changing to void I get:
afk_manager4.sp(904) : error 180: function return type differs from prototype. expected 'int', but got 'void'
Where did you get your updater.inc from? It doesn't seem like the stock one from
