Bukkit

What steps will reproduce the problem?
1) Install PermissionsEx
2) Pick a user to edit
3) Inherit group: builder
4) Inherit group: randompermissions
(Do it in such a way that ramdompermissions is on top in the permissions file - added last)
5) Add prefix to builder using Pex
6) Don't add prefix to randompermissions group

What is the expected output? What do you see instead?
Because randompermissions doesn't have a prefix ColorMe should next check that maybe builder has and use that.
Instead of having the prefix "builder" the poor user now has no prefix at all because ramdompermissions group doesn't have one defined.

What version of ColorMe are you using?
R: v3.8.1 for CB 1.5.2-R1.0

Do you have an error log of what happened? (server.log)
No errors. A design flaw.

Please provide any additional information below.

If you can advice me how to work around this problem I would appreciate it. I have a need to add temporary permissions to my users by adding them to extra groups and now ColorMe breaks my prefixes every time I do that.
