Answer : Nonqualified transactions are being rolled back.

Yikes.  No.

If you have a solid development environment then you should be able to make a duplicate of the database and allow developers to run their tests there.

A production database appears to ALWAYS be the quickest route to go, but it is also the most tricky and has the most risk.
