We have a custom field, whose default value was (TBD). For some reason, it decided to update the field to the default value at every opportunity, overwriting previous values with the default at transitions, edit, resolved. I removed the default value, and now it's inserting (None) instead of (TBD) still overwriting values. I created a new context with the same values, and the same behaviour continues.
I am preparing to delete the context, re-index, create a new context and associate it.
Has anyone else run into this type of behaviour, I'm more than a bit baffled. It's only happening on one project system wide, the other projects seem to be ok. Something must have gotten corrupted somewhere, but I have no idea where.
