I've been having the same problem where my supplies always goes into my main base (Command points / credits excluded, since they don't matter) instead of the base I want. I already had the intended base opened when applying the supplies.
In a few occasions, I tried to use muliple supplies boxes (of the same type). It appears that sometimes it works on my second/third try.
You're right about the Tiberium/Crystal but transfer wouldn't work for Power.
Any idea / tip how to make it right every time?
