This is OK, Teleportation will be initialized in the container. So far
good. (You can use NEEDS_BEX("Teleportation") macro with your teleport
engine to register the class to be initialized with the initializer
automagically).

Please provide the backtrace, that is _the_ most valuable information
about such thing.

I think this is OK. Class index is integer that is incremented for every
new class (not instance) factored in the class factory. It can,
therefore, be different from one run to another. Class indices that are
not registered with PhysicalActionContainerInitializer will not be
initialized,  but that is harmless (or should be).

Wouldn't it be easier to have a DeusExMachina teleport all bodies that
are too far away back where they should be? This way you have 1 extra
loop: in one, you detect the body ewnt nuts and create the Teleportation
action, in another loop, this action is performed and the body is
teleported.
