Is the TG jump capable?
I know that a TG with a single (jump capable) ship will jump through jumppoints to refuel
I am pretty sure, TGs will use jump-gates to refuel
I am not sure, TGs which contain a jump ship, but where not all ships are jump capable will jump through a jumppoint (although they should).
If a TG has no jumpship, but a jumpship is stationed at the jumppoint (i.e. a jump tender) they will *not* jump. Aurora can´t know, if the jump tender is still there, when the ship arrives at the jumppoint, after all.
