Just thinking, assuming that the system worked in the past, what could have caused it to change? Could the odd wiring be an attempt to compensate for the 1 battery that was different (maybe a different internal resistance)?

The batteries were chosen by someone who didn't know the proper battery type for our purpose. The wiring was done by someone who didn't know the proper way to wire for our purpose.
FWIW, I believe what happened is the batteries (probably not properly sized) have been deep cycled unbalanced and not completely topped up so many times that at least one of them kicked the bucket, which exaggerated the unbalanced issue.
Without further information on the state of the batteries, the loads you are running, and really how thoroughly they are being charged, there's nothing else we can tell you. We certainly can't diagnose any further issues until what we've said has been completed.
