And anyway, a moving actor's bounding box should never touch the ground - at least that's what we're preaching since A4 days. Otherwise you'll get collision with the ground when moving that entity.

Uh huh!?!.

Hint:
use two c_move instructions.
One for gravity, the other one for movement in x and y direction.
This hint is also given in the manual by the way.

It seemed here, for simply avoiding stuck conditions, 2 c_move invocations were unnecessary.

In A6, it almost seems that c_move / c_trace instructions are ridiculously expensive in terms of performance.
Maybe those instructions were optimized in A7.
