this is a strange one--the plastic baffle that screws inside the drum to grap/flip the clothes actually melted and came off?

?--as cheap as i can get a used dryer I'm nervous about spending $30 for a plastic baffle to have it happen again-------how can this happen and any reason to think it wont happen again from the same cause whatever that may be??--have u ever seen such--thank you
