This is:

- [X] a bug report

<?php

require __DIR__ . '/vendor/autoload.php';

$workbook = new \PhpOffice\PhpSpreadsheet\Spreadsheet();
$sheet = $workbook->getActiveSheet();
$sheet->getCell('A3')->setValue('A3');
$sheet->getCell('C1')->setValue('C1');
$sheet->removeRow(1, 2);
echo $workbook->getActiveSheet()->getCell('A1')->getValue(), "\n";
echo $workbook->getActiveSheet()->getCell('C1')->getValue(), "\n";

What is the expected behavior?

Script should output

What is the current behavior?

PhpSpreadsheet 1.6.0
