AdiIRC

Upon further investigation, this is related to /reload, the sample of code is this:

test

alias somealias {
if (condition) {
!.remove $qt($script)
var %u 1
}
.reload -rs $qt($script(pacman.mrc))
pacman
if (%u) .unload -rs $qt($script)
}

The value of $script points to Path/to/installer.mrc while $script(pacman.mrc) well, points to the pacman.mrc file
The /reload is causing adiirc to think the $script is no longer loaded ($script($script) is $null right after it, while it's non-$null before).
