[beheh]

The following options block from this power.log contains a player name not matching the Battletag. The generated HSReplay file is therefore missing the entity attribute on the Target block.

The resulting XML cannot be reimported using HSReplayDocument.from_xml_file, since it erros with the following stacktrace:
