Though I can't say for sure without looking at your model, a common cause of model crashes is having a geoset animation with no geoset assigned. If you check each geoset animation there should be a value in the "geoset ID" field. If it says none you can right click and delete the geoset animation to fix it. Another way you can handle something like wings is by attaching them via a dummy ability How to: Attach a Model or an Effect to a Unit
