I've been asked to release a project which has been written by someone else, then rewritten by another developer, and both have left the company.

I can't release it yet because there is an inconsistent bug throwing some values out.

We've got it running side by side with an older legacy system which it's going to replace. Before the 2nd developer left they added some logging to our live system to record both values so that they could be monitored to make sure there was no inconsistency.

There are some inconsistencies... however, when I run the same data through the new system and the legacy system in a test environment they both come out correct.

I've considered quitting...
