I would like to suggest the option to delay taking daily spins awarded via bomb drops by "vaulting them." This could be done my presenting the user a choice of "take now" or "vault for later"

You could even place a limit on how many a player can vault (i.e. 100 or 150.)

Doing this would serve two purposes...

1. Prevent someone from losing a bomb drop item because someone else takes that item while the first person is stuck in a daily spin

2. Allow for people in small or no crew and do not have bomb drop partners access to use these spinners during war or battle, giving them a chance to improve their score they may not otherwise have.
