Comments: The issue is in file "ExcelRangeBase.cs" in function "private void SplitFormulas(ExcelAddressBase address)": ``` //Bottom Range if (fRange._toRow > address._toRow) { if (fIsSet) { f = new ExcelWorksheet.Formulas(SourceCodeTokenizer.Default); f.Index = _worksheet.GetMaxShareFunctionIndex(false); f.IsArray = false; _worksheet._sharedFormulas.Add(f.Index, f); } f.StartCol = fRange._fromCol; f.StartRow = _toRow + 1; // THIS LINE IS BUGGY ``` has to be ``` //Bottom Range if (fRange._toRow > address._toRow) { if (fIsSet) { f = new ExcelWorksheet.Formulas(SourceCodeTokenizer.Default); f.Index = _worksheet.GetMaxShareFunctionIndex(false); f.IsArray = false; _worksheet._sharedFormulas.Add(f.Index, f); } f.StartCol = fRange._fromCol; f.StartRow = address._toRow + 1; // THIS FIXES THE CRASH ```
