Redmine

Hi,

I've just encountered a strange issue and I'd like to know if someone could help me to understand why it happened.

I made a modification on a top project's description and as a consequence, about 400 old tickets have been modified ! They all lost their target version, all tickets belong to the same subproject.

I'm using redmine 2.1, I've received notifications by email but when I check the history, those modifications don't appear at all.

This forge has been migrated from trac to redmine a while ago, could it be related ?

Thanks for your help.
