Two magnets came off my glass bed (again) so I changed adhesive this time to gorilla glue epoxy. It is not letting go now, but one of the magnets was just a little off and now won't sit in the hole in that corner. Great, I made it worse. Is there any way to pop it off the glass and try again? If not, where can I get another glass bed? The replacement parts section shows it's sold out. Is there an alternative upgraded bed avaliable, maybe with a larger heater?
