I've discovered that GreenHopper doesn't adjust its version statistics (e.g. Version Time Estimae/Time Spent/Time Remaining on the planning board) when an update fires a custom event, so I've removed all use of Custom Events from our workflows in order to try and keep our burndowns right, but it seems that there is no way to clean up historical data without toggling the fix version of every single issue.
Someone has just come to me with a burndown covering a four month release cycle that is showing 1063h remaining when running a filter shows 5 tickets with 19h 15m remaining. Understandably several people are now converned that other project burndowns may be similarly nonsensical. Note we use burndowns at the release level AND at the Sprint level,
So: Is there any way to force GreenHopper (5.4.2) to recalculate all its statistics for versions?
