Well this happens with default cube too (see pic). Also when removing the BP logic, the actors stack well. Perhaps is it due to a specific alignment from both actors ?
I tried with other meshes in my scene. It seems to happen too, but these are the only one to be so big and “stackable” : other meshes are tiny and less cubic (or there is only one), when dropping one over another they interpenetrate and just after the second one is “pushed” next to the first so they don’t stay one in the other.
