phys_reload_immediately

Set to 1 to reload resources and reconstruct physics of entities on the fly. May unexpectedly change behavior or crash the game, because game code is generally unaware of underlying resource reloads and may hold references to physics that may become invalid during resource reload. It is inherently harder for physics to deal with resource reloads because of persistent nature of objects being simulated (textures can be easily reloaded on the fly; if an entity holds a handle to a ragdoll body part, it may expect that handle to stay valid while the ragdoll exists)
