Warning message: "The number of rigid bodies in the simulation now exceed 65535"

There is a limitation in Nvidia PhysX about the number of rigid bodies that can collide with another rigid body that makes the simulation unstable/crash.

Unfortunately, there is no easy way for Golaem to prevent from this crash, so whenever the total number of rigid bodies in the simulation exceed 65535, this warning is displayed:
"The number of rigid bodies in the simulation now exceed 65535. If a single AABB object collides with all of them, the physX simulation will crash. Please contact support@mayacrowd.com if you experience a crash after this message."

When this warning occurs, the physics simulation may become unstable, so it is recommended to split the simulation in several crowdfields where each crowdfield uses a different phsyX locator.
