Strange things in Kiel channel/harbour (GWX)

[Henri II]

This is, I think, a kind of a bug report, I'm not sure if this is a known issue or not, I thought I'd let the GWX team know, just in case.
Returning from a patrol in Nov. 1940 I saw several search lights in the western entrance to the Kiel channel, when I came closer there was a small tanker with a british flag moored in the harbour which was illuminated by two german merchant ships. Don't know if this is a bug, or if it is intended to be some kind of a captured prize ship?
Another thing, which I think was a bug with the innitial release, is that uppon returning from a patrol to Kiel I often find several ships, at the western channel port and in Kiel itself, adrift and on fire, or already sunk. Once there were three capital ships drifting all over the harbour on fire or with decks awash.
