RESOLVED Towers of sand.. Bug?

[Asharru 3]

I recently experienced that if i place sand or gravel ( not by pressing V, but adding ) on flat ground im able to build a small tower yielding 10-17 of the same resource even if i just had 1 in my inventory after mining it. 

If i dig a small hole and place sand the ratio is 1:1 as i would expect. 

Guessing its some sort of exploit or bug ?

That was an even wilder result that i had. hehe.

At least i see it happends to others too then.

I would love to reproduce this, but I am a bit confused.  You are placing 10-17 sand on top of each other but only have one in inventory?  I think a bit of clarification may be in order.

what i did was: 

hold 1 sand in inventory hot bar.

i get the option to place/or add sand while using it in the hot bar.

i hold the mousebutton down and it build it self up.

hope that clarified it some more
