Ahsoka seems to choose a default turn until an enemy comes within her firing range. She may need her combat approach flag changed, or a more nuanced maneuver selection function added.
There is definitely a problem with using Biggs on both sides:
a. If Biggs on Team 1 has a character Droid or restricted EPT assigned, then Biggs on Team 2 cannot use them.
b. Biggs on Team 2 can shoot any ships on Team 1, even if Team 1 Biggs is in his front arc.
c. If Team 1 Biggs is in a Team 1 ship's front ARC along with Team 2 Biggs, that Team 1 ship cannot take any shots, presumably because she A) must shoot Biggs, and B) cannot shoot Biggs (friendly ship).
d. Team 1 Biggs gets all Stress from R4-D6 is they both have R4-D6 installed. Team 2 Biggs gets none, but does benefit from his R4-D6's ability.
I'll see if I can figure out what's going on with #2. #1 is too big for me, though.
I flew Horton, Biggs, and Norra (a glitch free list against the list below and had problems.
