We noticed that if a case is accidentally closed and then reopened, the OpenedBy (ixPersonOpenedBy column in the Bug table) value is modified to be the reopener rather than remaining the original opener.
Is there a reason this is done? Is the original opener preserved in some way other than case history?
This is causing a few problems for us. When this happens the original owner no longer has a tie to the case. They can't filter on cases they opened to find the original case. This seems like a bug to me.
