Making changes to a Node's CCK field via VBO also incorrectly resets Time Tracker information of that Node

So we're trying to use VBO along with the Time Tracker module, and we're running into a big problem.

Time Tracker allows for a Node to have timecard-like info attached to it. Every Node then 'knows' an overall Estimated Time, total Time has been logged towards it, and the difference between those two.

When we use VBO to edit a CCK text field (a preset list from a pulldown) it also resets the Estimated Time of the Node to Zero.

If we manually 'hand edit' a Node, this doesn't happen.

Having VBO delete other information attached to a Node that it's not set to edit is a little worrisome. ;-)

I'm going to try to setup an test Drupal install with just VBO & Time Tracker setup to verify the bug.
