Test Candidate (sans Deadly Neurotoxin)
Warming up the deadly neurotoxin...
for overlapping ships, only the end position of the moving ship is considered, not the position of the template.
for overlapping obstacles then both the move template itself and the ship's end position will indeed incur an effect
If the template touches it's the obstacle's effect on the maneuver (skip take action, possible damage, stress for debris).
If the ship's final position overlaps, then there is a further effect: no attack for asteroids, no flipping for K-Turns, S-Loops and T-Rolls.
There could be other things I'm not listing, that's just off the top of my head examples. Simply illustrations of the two different states.
The same two levels exist for overlapping other ships, there is just no effect from the first level.
