Hello,
how do I erase a physics object savely?

Do I have to just "ent_remove" them,
And what about the constraints?

phcon_remove removes them, is this nessecary when
all objects are erased?

Is there a garbage collection of "unused"physics objects, or
do they stay in the simulation?

I want to basically create physics objects with contraints and motors, and erase them quickly later
(they only live a few seconds), but without having to do level_load.
