I was trying to help a Jump Stab ship get to its destination and I had 2 tugs nearby, and decided to try something
Tug 1 - tractors JSS -- everythin is as expected, both ships moving at a speed consistant with total engine power and combined tonage
5 minutes later - wasn't sure this would work, but what happened was really unexpected
Tug 2 tractors Tug 1 - Tractor chain formed Tug 2 --> Tug 1 --> JSS
Speed Same as Tugs' base speed.
Seems like the code is averaging the tractoring ship and its grabbed ship, ignoring the ship tug 1 had grabbed, but still maintaining the link and moving it along with the tug combo.
