Thanks to the amazingly active users of AA, 2 bugs have been fixed today. One of them could log you out of the server if you use /aa_playerperms on a player with huge permission list, so I definitely recommend this upgrade
Version 1.56 =============
New maintenance version.
Fixed:
/aa_addredirect no longer causes errors when quotes are used for commands without parameters (such as /aa_redirect "command" "redirect_here")
/aa_playerperms no longer disconnects player who entered the command when the target player has a huge permissions list
