Only show download UI when downloading
reset this shit here because they allocate arrays based on the number of bones, and while they change when the model handle changes, the model handle might not have changed (because it might have just changed from an error to loaded)
On client model download, reload the model
Reallocate CCompositeParentSpaceState if bone count changed
CBodyGameSystem always RegisterToolsResourceListener
Try to deal with broken resource reloads by restoring their old models and clearing the list
