users not being removed from group...

helllo!

Having trouble getting this plugin to work quite right. 

First question - what's the grouptemp.use permission for? Should that be given to everyone?  

The problem i'm having - is that it'll add a person to the group just fine - but it never seems to remove them.   I've tried on myself (an admin level user) as well as a regular user.  The notification in chat pops, and I can confirm group membership.   No errors in console either.  I can peek at the data file it creates and there is data in there.   I am running Carbon (not oxide). 

Suggestions?
