1) Produced destroyers  possess a hyperdrive and they have according speed.
2) The cruiser given at the start of level 2 has a hyperdrive and according 
speed.
3) The destroyer left over from level 1 is shown to have a hyperdrive in fleet 
equipment screen (box in the middle, actual:1/max:1) but is shown with speed 6 
as it should.

It looks as if fleets/ships do not always move with the speed they are shown 
with now since you made the traders "catchable", this confuses me. (Am I faster 
or is the trader slower than shown ?) The cruiser really moves faster than the 
leftover destroyer at least. Same for produced destroyers.
Attached the start save for level 2 and the last one I still have from before.
