Help! Have a bug in holocms :S

When you try to change clothes or motto you get this error: Duplicate entry '826-ACH_A' for key 'PRIMARY'
Very strange is that it does not happen with all users..
Why? :S

And when I try to create a group: Object not found!

The requested URL was not found on this server. The link on the referring page seems to be wrong or outdated. Please inform the author of that page about the error.

If you think this is a server error, please contact the webmaster.
