Question 1
Was there a lot of air in the bag or container?
All causes, by frequency

- Air in the bag
Ice evaporates into the air and settles as frost in the bag ().
Next time: Press the air out of the bag or vacuum-seal it · Seal well
- Stored too long or temperature swings
Every swing drives out more moisture.
Next time: Note the date, use within a few months · Open the freezer rarely
