bugs intruduced in patches (probably still there)

[dmk]

1.14 engineer can't be called back to ship
1.15 stats showing, it was HOTFIXED, so none.
1.16 ai trade system damaged, crush after highway very probably
1.17 engineer don't repair again on boarded ships(as before 1.14),
ships could occupy exactly same space.
And there is cases when many ships stuck in exactly same place.
this happens in PLOT convoy mission(convoyed ships will stuck forever, needed to reload and follow him in highway very tight, before exit get in side) and could lead to boarding problems:
