If there's something specific to 11 digit numbers (other than the likely 32-bit wraparound issues) that's causing it to act as if 0 is given, then maybe there is a bug to fix if only to ensure it isn't part of some larger issue.
Yes, i agree, it's just that in his case, he have to used a loop with if $nick($chan,N,') == $1 or use the .pnick propriety
