Over the many hours of playing 0.7.1 with and without mods, i noticed some strange things with engine flame-outs.
*Disabled ships can have their engines disabled, and that causes the wreck to never decelerate.
*Sometimes disabled engines cause a non moving ship to move. I just had this happen to a cerberus in the simulator, something struck its engines while i was looking at a fighter squadron. the ship was strangely spinning out of control even though having not been moving at first.
And the odd rare case where the ship that has some but not all of its engines disabled suddenly has no limit on the speed at which it can turn, and simply spins into oblivion until it's other engine comes back online. Haven't found out how to replicate that, but it does happen with ships with maneuvering subsystems that increase speed/acceleration temporarily. Possibly the imbalance/placement of engines causes all the maneuvering subsystem thrust to go in that one engine, and it freaks out?
It has also only happened to the ship i was currently piloting. never an AI piloted ship.
