% of building materials from rubble

[xltim]

i need some building materials to finish my garage.
i have asked friends to send some, but have also been clearing rubble.
i have cleared over 200 pieces of rubble and only got 1 item
is this normal...
just seems very low to me.
i know its probably random, but i had the same problem trying to get items to craft weapons, took me 7 days to get enough to get the light saber.

Hey xltim,

7 days is pretty fast for getting the Laser sword.
You can get building materials from the zombies also.
Other than that, it seems normal to me. If I am not wrong, you can only get materials when you finish the rubble pile.
