I posted in the NYGM Tonnage thread sticky but so far no reply. So let me try here.
During my last patrol, I torpedoed a C-2 but then had to crash dive. When I surfaced some hours later, the C-2 was half submerged and dead in the water. As I approached to finish her off, the merchant sank on its own by the bow... its stern standing straight up before plunging into the depths.
However, I received no credit for the sinking.
Is this any sort of a known bug with the NYGM ship damage model? Thanks for any help......
