Large account balance suddenly appears in investment account
When reconciling an investment account against brokerage statement, one security suddenly shows a balance that is exactly $50K higher than it should be. I can trace the error all the way back to 2010 but not to any specific entry. A possible related event: my program shut down two days ago, had to reboot but no evidence of problems at that time. Should I completely reload the program so I don't get totally screwed up?
