Names of British ships in the destroyer division off Murmansk are wrong.
The names in-game are actually the names of real life battleships.
According to this (trustworthy) source - http://www.naval-history.net/WW1z05NorthRussia.htm, line 3811 of ScriptGrandCampaign.ini
should be changed from:
SUFlavorName = HMS Centurion|HMS Mars|HMS Lion|HMS Colossus|HMS Boscawen
to
SUFlavorName = HMS Sword Dance|HMS Glowworm|HMS Hyderabad|HMS Cassandra|HMS Medusa
Also, in case monitors ( = bombardment ships) exist in the unit list, the British Navy sent one to the Murmansk - the Humber.
