I think Ive encountered a problem with HMS Terror

It sailed into my scope on last nights patrol just of the East coast of UK,looked brilliant,but after 9 eels later it still wouldn't sink

I retreated to 4.5km distance determined to sink it,it was calm weather so I risked surfacing and using the deck gun,expecting to be met with a hail of shells from the stricken Terror.....but nothing

It never fired back once!

80 shells later from my 88mm and it still wouldn't sink

I know its a Monitor and tuff as old boots but surely I should have had more success than that???
