You mean that small coastal freighter? Always sinks with 1 hit as far as I know, 2 are gauranteed to blow it up. I actually
lowered the HP on that one.
Updated to 1.1; freighters are a little more cooperative, T3 more balanced. Link in the first post.
* yes, I see. The small one doesn't want to sink by the stern. Engine room hit or anywhere in front of the bridge sinks her instantly though.
For the record that's stock behaviour. Nothing to do with the mod.
See if I can fix that.
