Prior to 2b16 there was a bug in the audio components. If a moving model is placed in a model and there is no Audio.cmp component in the model it will crash because audio is not initialized. The required workaround is to add /DNOAUDIO to your preprocessor line for the model. In 2b16 the model when run will exit and give an error stating that /DNOAUDIO must be added to the compile line. A more complete solution is being worked on for a later release.
