[Programming Help] - Issues while playing chart replay

Repeated “Array is unallocated” message during Chart Replay I am using Sierra Chart 2947 64-bit, Revision 58042. During Chart Replay on a 5-minute CME British Pound futures chart, the Message Log repeatedly reports: “Array is unallocated.” The chart and custom ACSIL studies were operating normally earlier today. The problem then began occurring repeatedly during replay/chart recalculation. As a diagnostic test I restarted Sierra Chart in Safe Mode. Help > About Sierra Chart confirms: Safe Mode: Yes However, the “Array is unallocated” messages continue to occur in Safe Mode during Standard Replay. Could you please identify what component/study is generating the “Array is unallocated” message, or advise how I can determine its source? I do not want to remove or modify working studies unnecessarily because the study chain was functioning correctly before this started. I can provide the complete Message Log and chartbook if required.
