I'm not sure what bugs you already know of, but I'll list what I have found so far...

1 The links in the whois/details window are broken under options and links. Here's some quick examples of what happens when you click the links:
 

To [Mybot]: tell Mybot history Myname
[Mybot]: /tell Mybot !help

To [Mybot]: cc addbuddy Myname
[Mybot]: /tell Mybot !help

To [Mybot]: start http://auno.org/ao/char.php?dimension=2&name=myname
[Mybot]: /tell Mybot !help

2 !shortcuts add command doesn't work. It doesn't give any feedback, doesn't add the shortcut.

3 All of the links to change Guild Rank bot permissions are broken in !security levels. Here's an example; Clicking on Org Rank general to be Admin, you get:

To [Mybot]: 192
[Mybot]: /tell Mybot !help

4 I know this has been mentioned, but you can't change the relay name from guild chat. Oh, and exist is spelled wrong when it gives you the error.

To [Mybot]: set Relay Gcname <name>
[Mybot]: Setting Gcname for module Relay does not exisit.

I'm pretty sure there was multiple other things I noticed, I just can't remember at this time. I'll post when/if I think of them.

I hope this helps, just wanted to make you guys aware if you didn't already know.

To [Mybot]: security changelevel Department President 255
[Mybot]: Invalid input for changelevel command.
To [Mybot]: security changelevel Department General 192
[Mybot]: Invalid input for changelevel command.

Seems the commands arn't working either, even though the links are broken.

on the raid side of things

teamadmin has a typo somewhere making teamadmin GUI 100% useless.  All links broken.  team related commands seem to function however.

caller add does not work at all.

this popped up in 0.5 and is not fixed in 0.5.1

To [bot]: !online shade
bot: Error: The module Profession_Core returned the error 'shade' is not a valid profession name or shortcut.
