We already know thanx Brag
Been around 3 similar threads in the last couple of weeks
Rubini and myself are working on it now
As I said before its part stock and part GWX problem
Below is a stock T3 after attacking then leaving convoy then going back
The greater the time between visits the worse the sinking
The same ships in stock are affected in GWX only slightly worse
New ships made from those stock ships also show the same trait
The problem is more noticable now with many of the new ships as harbour traffic
Of course in stock there were none so you never saw it
