This is somit that would be nice, altho no idea if possible
i run a raidbot and making changed can be anoying because they have to rejoin the pgroup each time
i was hopeing for a command that will reload the modules directory or maybe entire bot with out loging the character out and in

Technically troublesome is putting it mildly. Afaik it's more or less downright impossible to do reloading like this in PHP by means of PHP code.
